The human machine has three major sources of input energy: carbohydrates (bread, grains and simples sugars such as those in milk and fruit), protein (meat, legumes) and fats (too many kinds to name). When the body consumes one of these energy sources, the food molecules are broken down into smaller pieces using enzymes--doing so releases the stored energy in the food and provides small pieces from which to build more complex molecules. \n\nEach food source has a specific role to play in metabolism. Carbohydrates are the dietary source of an important sugar called glucose. In fact, carbohydrates, such as the starch in potatoes, are simply very long chains of connected glucose molecules. Glucose is so important because it is the only source of fuel for the brain, red blood cells and several other tissues. Your brain uses about 120 grams of glucose per day. Any carbohydrate consumed in excess of what is needed for running the body's basic metabolic processes is converted to glycogen or fat for long term storage.

Glucose is important to the body because it is broken down into just water and carbon dioxide in the process of oxidative phosphorylation in the mitochondria of your cells-this requires oxygen..  This is where your body gets 95% of it's evergy-for example, runners use oxydative phosphorylation (aerobic energy) and can go steadily for 26 miles (or more)-while weightlifters when lifting use primarily anaerobic energy (without oxygen)-that only can give energy for a minute or so.  WIthout aerobic metabolism you would die in a few minutes.  So, glucose plus oxygen is where you get energy, and it happens in the mitochondria of cells.  Cyanide interfers with this reaction in the mitochondria, so that oxygen cannot be used to make energy (so cyanide primarily works against oxygen, but since it's glucose + oxygen that is burned to make the energy, is might as well work against glucose as well).  Burning glucose for energy using oxygen is exactly the same as burning fuel in a fire.  If you start a fire, but keep it from getting oxygen, it'll go out- cyanide starves your body of the oxygen, so *your* fire goes out.

ATP expelling water.  Glucose is broken down to make ATP and the process consumes oxygen, while expelling water. :)

In Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose.  In cellular respiration,  glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules.

One mole of glucose produces approximately 7.6 moles of ATP and one mole of ATP releases approximately 25 calories.

To put it simply, they're opposites.  Respiration consumes glucose and oxygen and releases energy and carbon dioxide.  Photosynthesis uses sunlight (i.e. energy) and consumes carbon dioxide and produces oxygen and glucose (i.e. stored energy).  In other words, photosynthesis is the process of storing energy and respiration is the process of releasing that energy.

It comes from the carbohydrates we eat.\nFor example: \n1. from honey \n2. from sugar\n3. from bread\n4. from syrups.\nIt may come also from internal sources like from liver glycogen (this word means that it can generate glucose), from lactate (through the "reverse" of glycolysis), from glycerol that comes from tri-glycerides (fats and oils), from glucogenic amino acids such as alanine. \nOne of the most beautiful and amazing metabolic web is the use and formation of "glucose"!

When you say activation energy I presume you're talking about the 2 ATP used? Those 2 ATP are part of the first step of aerobic respiration, glycolysis.\n\nIn glycolysis, we start with a molecule of glucose, C6H12O6\n1) 2 ATP are used\n2) 2 NADH are produced\n3) 4 ATP are produced\n4) 2 pyruvate are formed

Cell Respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.

D-glucose (or just glucose, or dextrose) is the "normal" carbohydrate that biochemistry uses as both energy and as a building block for starches, cellulose etc.  \nL-glucose is it's "non-superimposable mirror image".  It is the left-handed version of glucose (if you can accept the notion that it is "right handed"\nL-glucose plays no biochemical role that I know of.

This is basic biochemistry.  All cells (really, all bacteria, all fungi, all plants, all animals) use glucose or other simple sugars as a main source of fuel for energy generation.  (Some will argue that plants actually produce glucose, they both produce and consume it).  The process of glucose breakdown is glycolysis, and it generates energy in the form of ATP, and converts molecules such as NADH to NAD+.  This electron loss gets passed through the electron transport chain  in the mitocondria to generate more ATP.  \n\nCarbohydrates include complex and simple sugars.  Simple sugars can be broken down directly in cells, there are specific receptors that bring in the sugar.  Complex carbs such sucrose (a disaccryide, or a molecule containing two simple sugars) just contain more than one simple sugar in a chain.  They are broken down in the gut by specific enzymes that break the chain and release simple sugars.  Starch is a form of a carbohydrate, but not digestable to mammals, because we lack the enzyme to break it down.  Some bacteria don't though, and they live inside the gut of some mammals such as cows, and when cows eat grass, the starch is broken down by the bacteria and some of it is released into the gut.  So thats why mammalian herbavours exist.  \n\nFat metabolism.  Fats are long carbon chain connected at one end, usually three are connected to glycerol, this is called a triglyceride, and is a perferred form of storage.  Fats are broken down by chopping the carbon chain and generating energy.  Fat burning is slow and fat is a backup fuel source; the primary being simple sugars. \n\nProtein metabolism.  Proteins are digested by proteases in the gut, and the free amino acids are absorbed into the blood stream, where they can enter cells.  Cells can utilize amino acids for energy, but it's not that efficient.  Instead cells utilized amino acids for building new proteins; including the 'essential' amino acids, those that can't be generated by mammalian cells (we lack the enzymes).  So some amino acids are absolutely critical for our well-being.  \n\nLow carb diets simply don't have much carbs, and force the body to switch to fat to burn (in theory).  In reality it doesn't work too well.  During initial exercise, muscles use glycogen, a stored form of glucose, for energy. Also fat is utilized, and a bit of protein.  After 2 hours of exercise (or so, depending on the person), muscle glycogen is depleted, and body must use fat and glucose and protein.  If you do not intake glucose during this exertion, your performance will rapidly drop off; you can only burn so much fat at a time.  So the best advice for fat burning is exercise (at 60-70% max heart rate) for an hour or two, 3, 4x a week, and keep hydrated with water or gatoraid.  \n\nHigh carb diets make it easier for long term exercise by increasing the amount of muscle glycogen.

i assume "respiration" in your context refer to cellular respiration..\n\ncellular respiration in simple terms breaks down glucose and produce energy in forms of adenosine triphosphates.(ATPs). ATPs are the energy currency in the body and the breakdown of ATPs provide the energy needed for other metabolic processes, including digestion. Looking at it another way, digestion of complex nutrients like carbohydrates produces glucose, which is the respiratory substrate..\n\nDiffusion - oxygen required for aerobic respiration enters individual cells by diffusion. Waste products of aerobic respiration such as co2 leave the cells by diffusion into the bloodstream.  in general, diffusion is a passive process which does not require energy from ATPs, be it facilitated diffusion or simple diffusion, both are exergonic processes.\n\nthe circulatory system would carry the materials needed for aerobic respiration, eg oxygen and glucose to the individual cells, oxygen in form of oxyhaemoglobin in red blood cells. The circulatory system also carries the waste products, eg co2 away for excretion. \nThe circulatory system requires the pump, i.e. the heart to work, and the cardiac muscles require ATPs from respiration for contraction.\n\nhope u can see that they are all interrelated now..=)

Anabolism is the part of metabolism that refers to building of molecules, therefore, it would seem reasonable to anser there strangely worded questions thusly:\n\n1) since Amino Acids are used to build proteins and peptides, anabolism of amino acids yields proteins and peptides;\n\n2) since glucose is used to build glycogen, anabolism of glucoos will yield glycogen.\n\nGood luck!

The answer is (D) simple sugars.  However, cells must break down glucose through cellular respiration (glycolysis or fermentation) to create ATP, which is the energy molecule used for cell processes.

A solution could absorb energy from photons, but they are a measurement of light. Rather than being absorbed, for example, the solar radiation breaks down chemicals in the leaves of plants which allows the plants to form food. Rather than being absorbed, the energy causes a change, such as increased temperature and chemical reaction.
