aerobic respiration works by breaking down glucose into carbon dioxide and water molecules.  This provides the cell a chemical form of energy called ATP which is used for all cellular functions.  The way it works is by a series of chemical reactions that creates ATP molecules by breaking bonds in the glucose.  It is often called a step wise reaction because it take several steps.  The reason for this is so all the engery is not realeased at onces creating a lot of heat.  (For example burning sugar realeases all the enrgey quickly, but creates a lot of wasted heat)  First the gluclose is broken down into pyruciv acid in the cytoplasam, which creates 2 ATP, then in the mitochondria it is broken down further sending molecueles with Hydrogen atoms to the Electron Transport Chain where oxygen is needed.  This is why it is call aerobic respiration.  This is  the main ATP (energy) producing step.  Overall for each glucose molecule you get a net gain of about 32 ATPs I believe.  \n\nIf you want more details, just look it up in a biology book.  I am sure there are great diagrams you could look at to help see the process.

Is a simple culture enough?\nthe anerobic won't grow in air the aerobic will grow and give off O2. Yeasts will give off CO2.\nYou may need an autoclave to maintain temperature.\n{sorry not to be more helpful}

There are multiple methods of ATP generation.\n\nGlycolisis in which carbohydrates are converted to pyruvate and generate a small amount of ATP.\n\nAerobic respiration, which starts with the pyrvuate, uses oxygen as the terminal electron acceptor and generates large amounts of ATP.\n\nAnerobic respiratin WHICH IS NOT FERMENTATION I SAY THIS IN ALL CAPS BECAUSE PEOPLE FREQUENTLY SAY THAT IT IS.  Anaerobic respiration uses the pyruvate as the initial energy source, and instead of oxygen uses alternative terminal electron acceptors such as DMSO or Nitrate or a number of other things.  Anaerobic respiration generates less energy than aerobic respiration generates.\n\nFermentation starts with carbohydrates and ends with the production of various acids and solvents (lactic acid, ethanol, butyric acid, acetic acid, butanol, acetone etc).   Fermentation produces ATP, but less than respiration does.

All living organisms require energy to function. This energy may be obtained from the consumed foods. The most efficient way for cells to harvest energy stored in food is through cellular respiration, a catabolic pathway for the production of adenosine triphosphate, or ATP. ATP is a high-energy molecule and it is expended by working cells. The starting material of cellular respiration is the sugar glucose, which has energy stored in its chemical bonds. \n\nThere are actually two general types of respiration, aerobic and anaerobic. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration does not use oxygen. Both types of cell respiration begin with the process of glycolysis, after which the two diverge. \n\n\nAerobic respiration is more efficient and more complicated than anaerobic respiration. Aerobic respiration uses oxygen and glucose to produce carbon dioxide, water, and ATP. More precisely, this process involves six oxygen molecules for every sugar molecule:\n6O2 + C6H12O6 6CO2 + 6H2O + ATP (energy)\n\nAerobic respiration requires oxygen. However, some organisms live in places where oxygen is not always present. Similarly, under extreme exertion, muscle cells may run out of oxygen. Anaerobic respiration is a form of respiration that can function without oxygen.\n\nIn the absence of O2, organisms continue to carry out glycolysis, since glycolysis does not use oxygen in its chemical process. But glycolysis does require NAD+. In aerobic respiration, the electron transport chain turns NADH back to NAD+ with the aid of oxygen, thereby averting any NAD+ shortage and allowing glycolysis to take place. In anaerobic respiration, cells must find another way to turn NADH back to NAD+. \n\nThis “other way” is called fermentation. Fermentation’s goal is not to produce additional energy, but merely to replenish NAD+ supplies so that glycolysis can continue churning out its slow but steady stream of ATP. Because pyruvates are not needed in anaerobic respiration, fermentation uses them to help regenerate NAD+. While employing the pyruvates in this way does allow glycolysis to continue, it also results in the loss of the considerable energy contained in the pyruvate sugars. \n\nThere are two principle forms of fermentation: lactic acid fermentation and alcoholic fermentation. \n\nIn lactic acid fermentation, pyruvate is converted to a three-carbon compound called lactic acid: \npyruvate + NADH lactic acid + NAD+\n\nIn this reaction, the hydrogen from the NADH molecule is transferred to the pyruvate molecule. \n\nLactic acid fermentation is common in fungi and bacteria. Lactic acid fermentation also takes place in human muscle cells when strenuous exercise causes temporary oxygen shortages. Since lactic acid is a toxic substance, its buildup in the muscles produces fatigue and soreness. \n\nAnother route to NAD+ produces alcohol (ethanol) as a by-product:\n\npyruvate + NADH ethyl alcohol + NAD+ + CO2\n\nAlcoholic fermentation is the source of ethyl alcohol present in wines and liquors. It also accounts for the bubbles in bread. When yeast in bread dough runs out of oxygen, it goes through alcoholic fermentation, producing carbon dioxide. These carbon dioxide bubbles create spaces in the dough and cause it to rise. \n\nLike lactic acid, the ethanol produced by alcoholic fermentation is toxic. When ethanol levels rise to about 12 percent, the yeast dies.

photosythesis and aerobic cell respiration are REVERSE equations of each other and would probably be described as the TWO most important chemical equations on the planet, (but all equations are important!). Plants are crucial to aerobic life on earth!\n\nPHOTOSYNTHESIS is a synthesis reaction taking small inorganic molecules to make a larger organic molecule (and inorganic byproduct, oxygen. It occurs in the chloroplast of green plants (with chlorophyll pigment) and some photosynthetic bacteria:\n\nEQUATION in words, not formulas: \n\ncarbon dioxide plus water makes glucose sugar (carbs) and oxygen gas (but it needs the sunproper temp, chlorophyll and proper nutirents in the soil to occur\n\nAEROBIC CELL RESPIRATION is a catabolic-decomposition reaction where a larger organic molecule (glucose) is broken down into smaller inorganic molecules (CO2 and H2O) and occurs in the mitochondria of the cell, plant or animal:\n\nEQUATION IN WORDS, not formulas: \n\nglucose (in the presence of oxygen) converts to carbon dioxide, water, ATP (energy molecule) and heat. This is AEROBIC, not anaerobic.\n\nThus plants are able to "take care of themselves." They can make their own glucose from the sun, but then can do cell respiration from glucose they made from photosynthesis. We can't do photosynthesis, so we have to go eat carbs and are thus called heterotrophs.  It's why plants are called autotroph producers.  Anything that eats plants or animals is called a consumer or heterotroph.

glycolisis is an anaerobic process not required O2 to function, while the Krebs Cycle and electron transport occur in the walls of the mitochondria where oxygen is used and yielded. Further, glycolisis occurs in the cytoplasm, a place of little or no oxygen. \n\nThe next step in anaerobic cell respiration is fermentation it can be lactic in most animals or alcoholic in most plants

Aerobic respiration requires, of course, oxygen to proceed. After glucose breaks down into two molecules of pyruvate (glycolysis), the pyruvate enters the mitochondria to take part in the citric acid cycle (aka. krebs cycle). The krebs cycle makes energy in the form of ATP, NADH, and FADH2. NADH and FADH2 are high energy electron carriers that make more ATP in the electron transport chain, which happens in the inner mitochondrial membrane and uses oxygen as a final electron acceptor. Thus, you can get about a 36-38 ATP yield from aerobic respiration. Comparatively, anaerobic respiration happens without oxygen and only produces 2 ATP molecules per glucose. This happens through fermentation, which produces lactate/lactic acid in humans (so it's not that great, since it causes sore muscles, etc.). Aerobic respiration produces much more energy than anaerobic repiration does, even though glucose is the starting point for both.

18. D. Oxygen and energy (ATP) are products of aerobic respiration, whcih takes place in the mitocondria.\n\n19. B. The cell membrane is called a LIPID BILAYER. which has 2 layers of phospholipds. the hydrphobic tails in the center. and the 2 heads facing out side the cell and inside the cell. the inner layer would have the head facing the inside of the cell.\n\n20. A. the bactera (monerans) were one of the earliest forms of life. The had the earliest form of sexual reproduction by exchanging DNA with another bacterium through their membranes. They were also mobile (getting around from place to place). For example, some bacteria have flagela, which whip around for them to move. an getting energy from the sun... hmm. well. im not sure if bacteria can photosynthesize. but im 100% sure they can get energy from the sun INDIRECTLY through cellular respiration.

Kreb cycle and glycolysis - is what I initially answered\n\nHowever, if it is a standard test/textbook question the questioner is asking, then the answer is probably going to be 2 different mechanisms/pathways. It probably is going to be AEROBIC and ANAEROBIC metabolism.

A) Aerobic respiration\n\nNeurons use an enormous amount of ATP to operate the Na+/K+ pump. Aerobic respiration produces an enormous amount of ATP (36 ATP per 1 glucose). Neurons therefore utilize aerobic respiration.\n\nThe other answers do not make sense. \n\nAnaerobic glycolysis provides very little ATP (2 ATP per 1 glucose). Creatine phosphate provides little ATP and is localized in the muscle. Stored glycogen only directly provides glucose for glycolysis. Catabolism of DNA would lead to the death of the organism, or at least mutagenesis.
