True, molecules exist EVERYWHERE.  EVERYTHING is composed of molecules.  Molecules contain the information and properties of the structure it's building.  For example, your skin has the properties that say "i'm skin and i'm soft" and metal would have properties that say "i'm metal and i'm solid".  Ect.  I hope this kind of helps.\n\n--luis

Every single function inside your body is based on biochemistry!\n\nYour blood, muscles, metabolism, respiratory system, and more... They all involve your body's cells and various chemicals, all working together to keep your body running, so you are able to exert yourself through physical activity.

breathing, thought, eating, excersize, emotion, sickness, immunity and basically everything a human does would have some kind of chemistry involved considering we are multicellular organisms made up of many elements such as oxygen, calcium, carbon, nitrogen etc

Water has numerous uses inside the human body. You cannot live without water, your organs will fail and shutdown. That would probably be the most important contribution water has to the human body, keeping you alive. \n\nWater is a good solvent, high surface tension, able to dissolve many substances, and high boiling boint --- all of these reasons allow organic molecules to be transported in water. Also, think about metabolism. It carries out the chemical reactions that are occuring inside the body. The outside of the cells are in contact with the water, keeping dehydration from occuring.

look around "Life is chemistry"\n1- the air we breathe diffuse in our tissue so gas exchange occurs this by chemistry.\n2- the food we eat is treated with chemical cpds to kill pests (in agriculture)  & increase it's expiary (can food).\n3- plants keep our life possible on the planet by photosynthesis (it absorb CO2 & release O2) this is chemistry.\n4- chmistry used in drugs preparation.\n5- chemiacal cpds used as fertilizers,detergants,sterilizers...etc\n6- the perfume u use made by chem.\n7- chemistry control our body (enzymes,hormones,DNA etc) this is biochemistry.\n                          Finally if u look around u will found that nothing \n                                             is not chemistry.

No, the human body is a very large collection of atoms, the cells are made up of all sorts of things taht each could be divided into smaller things and that on the other hand maybe can bedivided into smaller things until you find that all that is left is atoms.

There are no recommended daily allowances for nucleic acids.  You are getting amino acids with protiens you eat and they are the building blocks of necleic acids.  The body will break them down to amino acids to absorb them anyway.

DNA is the building blocks of life (I know you've heard that one). Basically, DNA encodes everything. It's what creates cells.\n\nIn a nutshell, DNA is comprised of a basic 5-carbon sugar with an attached nucleic acid (one of four, adanine, guinine, cytosine, and thiamine). These form long chaings that if stretched out fully would encompass the earth around 5 times. They encode (in a lengthy process) for protiens and certain protein chains that in the end, make your cells. And more cells, and more, until you get an organ. Enough organs and you get an organism. \n\n-Eric

As Beare85 said, the matter comes in as nutrients or food. Metabolism consists a series of reactions that happens in the body and in cells, taking in food (potato, beef and so on), brakes them down into the smallest biological molecules (particles such as proteins, carbohydrates, fat, and other minerals and vita mines, while storing the energy of those bonds), then uses them as building blocks for their functions. In the body, a lot of the breaking down happens in the digestive system, and is spread through the body in the blood. Cells absorb nitriente mostly as building blocks already. Cells are mostly proteins, lipids (fat) and water. It all comes from food.

This is a very perceptive question. Well done! You deserve an answer.\n\nWe are the life force, life energy, divine energy,elan vital, (that's french), whatever you want to call it. The energy peculiar to life which acts upon material in the physical universe and animates it, mobilizes it and changes it.\nBut we are suscepable to alteration in character or vibration and can become enturbulated. Hence the mess we sometimes make of the physical universe.\nSo there is a similarity to energy in the physical universe therfore batteries is a great analogy. I like it.

Chemistry explains at the atom/molecule/electron level how atoms interact.  For medicine, a good understanding of chemistry lets us know exactly how the medicine works.  This is useful to develop other medicines that work but are safer.

Cells are the basic building blocks of life. Their main goal is to maintain homeostasis, the way this is done is by using organic and inorganic molecules. Organic molecules are compounds containing carbons, whereas inorganic molecules are compounds that don't have carbon.  \n\nOne of the cells' main function is to make energy. The way it makes energy is via the Kreb Cycle, where it uses  organic molecules such as glucose, and breaks it down into energy ATP  another organic molecule. \n\nAnother function is Reproduction/Replication...cells use RNA (organic molecule) to make DNA (organic molecule).\n\nIf you look at cells on a larger scale, such as tissues...  note that there are four types of tissues: nervous tissues, connective tissue, muscle tissue, and  epidermal tissue.... if you look at the nervous tissue in order for a signal to be transmitted from the brain to the muscle,  neurons have to be able to send the message from the brain to the muscle using action potentials, which use inorganic molecules such as sodium and potassium, in the ion channels in a voltage sensitive gate.  Due to diffusion and osmosis, the ion gates open and close based on concentration levels of sodium and potassium and also based on the action potential. \n\nNote: that you question is very broad and requires not only the knowledge of basic biology but systemic physiology as well. If you want more answers or something you may email me.

hi,\n\nas i remember:\n\n - molecules behave as rigid objects (spheres, if you like)that move according to newtonian physics\n\n -  collisions between molecule/molecule and molecule/container are perfectly elastic (i.e. energy is conserved in all collisions)\n\n  - the size of the particle is much less than their typical separation (i.e. collisions are infrequent).  this leads to the related feature that there are no long-range interactions betweeen molecules.\n\n - the average kinetic energy of a collection of molecules is a function of only the temperature.

study of the substances found in living organisms, and of the chemical reactions underlying life processes. This science is a branch of both chemistry and biology; the prefix bio- comes from bios, the Greek word for “life.” The chief goal of biochemistry is to understand the structure and behavior of biomolecules. These are the carbon-containing compounds that make up the various parts of the living cell and carry out the chemical reactions that enable it to grow, maintain and reproduce itself, and use and store energy.\n\nA vast array of biomolecules is present in the cell. The structure of each biomolecule determines in what chemical reactions it is able to participate, and hence what role it plays in the cell's life processes. Among the most important classes of biomolecules are nucleic acids, proteins, carbohydrates, and lipids.\n\nNucleic acids are responsible for storing and transferring genetic information. They are enormous molecules made up of long strands of subunits, called bases, that are arranged in a precise sequence. These are “read” by other components of the cell and used as a guide in making proteins.\n\nProteins (see Protein) are large molecules built up of small subunits called amino acids. Using only 20 different amino acids, a cell constructs thousands of different proteins, each of which has a highly specialized role in the cell. The proteins of greatest interest to biochemists are the enzymes (see Enzyme), which are the “worker” molecules of the cell. These enzymes serve as promoters, or catalysts, of chemical reactions.\n\nCarbohydrates (see Carbohydrate) are the basic fuel molecules of the cell. They contain carbon, hydrogen, and oxygen in approximately equal amounts. Green plants and some bacteria use a process known as photosynthesis to make simple carbohydrates (sugars) from carbon dioxide, water, and sunlight. Animals, however, obtain their carbohydrates from foods. Once a cell possesses carbohydrates, it may break them down to yield chemical energy or use them as raw material to produce other biomolecules.\n\nLipids are fatty substances that play a variety of roles in the cell. Some are held in storage for use as high-energy fuel; others serve as essential components of the cell membrane.\n\nBiomolecules of many other types are also found in cells. These compounds perform such diverse duties as transporting energy from one location in the cell to another, harnessing the energy of sunlight to drive chemical reactions, and serving as helper molecules (cofactors) for enzyme action. All these biomolecules, and the cell itself, are in a state of constant change. In fact, a cell cannot maintain its health unless it is continually forming and breaking down proteins, carbohydrates, and lipids; repairing damaged nucleic acids; and using and storing energy. These active, energy-linked processes of change are collectively called metabolism. One major aim of biochemistry is to understand metabolism well enough to predict and control changes that occur in cells. Biochemical studies have yielded such benefits as treatments for many metabolic diseases, antibiotics to combat bacteria, and methods to boost industrial and agricultural productivity. These advances have been augmented in recent years by the use of genetic engineering techniques.

That's a HUGE question you're asking, if I understand it correctly.  While the body is made up mostly of water, there's also an *enormous* number of biochemicals in the human body working in extremely complex ways, all of which affect human behavior, from whether your hungry to the color of your eyes to whether you're alive or dead.  Even biochemists don't know yet exactly what they all are and how they all work.\n\nA (very) partial list:\n\nhemoglobin\nserotonin\nbrain natriuretic peptide\nadenosine triphosphate\nacid phosphatase\nD-oxy-ribonucleic acid (DNA)\ntriglyceride\npyruvate dehydrogenase\nsuccinyl coenzyme-A synthetase\n1-aminocyclopropane-1-carboxylic acid\nbacteriorhodopsin\nbeta-hydroxy beta-methylbutyrate\nfarnesyl pyrophosphate, geranyl pyrophosphate and other acyclic sesquiterpines\n\n...to name a very few.

Every living cell performs continuously thousands of different chemical reactions. Taken nutrients are transformed into a multitude of cell specific components. In this way, sugars, amino acids and their precursors, organic acids, nucleotides, lipids and other substances are produced. The totality of these reactions is summarized as the cell metabolism. In every chemical reaction, a bond is either formed or broken. This process does generally consume energy, consequently, the cell's metabolism and its energy balance to have be regarded as interdependent parameters. Every covalent bond of a molecule contains energy that is set free upon breaking down and that can subsequently be used for other purposes. It could, for example, be used for the formation of a new bond or it could be transformed into another form of energy like movement, warmth, light or electrical energy. Most chemical bonds and nearly all that occur within a cell are stable under physiological conditions. Hence, activation energy is needed for the break-down of a molecule. In chemical laboratories, high temperatures, high pressures or certain inorganic or organic catalysts are normally used. \n\nThe term activation energy refers to the minimum amount of energy required for a chemical reaction to occur. Most reactions require that atoms and molecules crash into each other with a great deal of force. These violent collisions must occur with enough energy to cause the chemical bonds within the molecules to be weakened or broken. When this occurs, the reactant molecules form an activated complex from which the product molecules are formed. Depending on the strength of the bonds within the reactant molecules the activation energy can be quite large, making the activated complex difficult to form.

We, along with everything else in the world, are made up of atoms. Atoms are the basic building block of all matter.  The periodic table lists the different "elements" in the universe. Each element is made of a unique kind of atom, and there are no other kinds. For example, you can have oxygen atoms, or carbon atoms, but there are no plastic atoms. Anything more complex than the elements is made by sticking atoms together to form molecules - you *can* have a plastic molecule.\n\nAtoms consist of a nucleus, which contains protons (positively charged particles) and neutrons (no electrical charge.) The protons and neutrons are the heavy part of an atom. Electrons (negatively charged particles) orbit around the nucleus. \n\nThere are always the same number of protons and electrons, so the positive and negative charge cancel each other out. The number of neutrons can vary. Adding the number of protons and neutrons will give you the "atomic mass" of an element.
