1. In fermentation, pyruvic acid molecules from the glycolysis cycle are turned into other chemical compounds, and a little bit of energy (only two ATP molecules per molecule of glucose – actually four are produced in glycolysis, but two are used up before it reaches this stage) is produced, IN THE ABSENCE OF OXYGEN!\n2. It takes place in the cytoplasm.\n3. all eukaryotes, to some degree\n4. wine, beer, cheese, medications...all are products of fermentation

I know the answer. The total quantity of ATP in the human body is about 0.1 mole. The energy used by human cells requires the hydrolysis of 200 to 300 moles of ATP daily. This means that each ATP molecule is recycled 2000 to 3000 times during a single day. ATP cannot be stored, hence its consumption must closely follow its synthesis. On a per-hour basis, 1 kilogram of ATP is created, processed and then recycled in the body.

Remember, mitochodria are the locale for oxidative respiration.  Glucose and fatty acids are broken down to pyruvate during glycolysis, which occurs in the cell cytoplasm and does not require oxygen. The pyruvate molecules are transported into the mitochodria where they're utlized to produce energy (ATP) via the Kreb's cycle (which occurs in the mitochodria).  This process requires oxygen, thus the term "oxidative respiration".  Lack of oxygen results in loss of ATP production, and utlimately cell death.

fermentation in bacteria is anaerobic respiration, the only difference being the by-product.  In humans, what we make during anaerobic respiration is lactic acid (which gives you cramps).  in yeast, they make alcohol.  Since prokaryotic organisms have no mitochondria, anaerobic respiration just takes place in the cytoplasm.

Complete oxidation of a glucose molecule produces 38 ATPs but 2 ATPs are used early in the cycle, so there is a net yield of 36 ATPs.

Glycolysis.\n\nOne molecule of glucose is broken down into two molecules of pyruvic acid generating energy in the form of ATP and NADH. This is one of the most common metablic pathways known, being found in the majority of living organisms.

From respiration: Here, glucose molecules in the cell are broken down; the molecules have strong bond between them and so when they are broken, energy is provided(by mitochondria) and when new molecules are formed, energy is released, which the cell uses for various processes.\n\nFrom protein synthesis: It occurs on the ribosomes in the cytoplasm, and aminoacids are combined to form proteins and this releases energy.\n\nFrom ATP(adenosine tri-phosphate): The ATP molecule is a packet of energy which stores the energy released during any process going on in the cell and then releases the energy as and when required by the cell.

The answer is C.  Glucose + oxygen are metabolized through glycolysis, the krebs cycle and electron transport chain to produce a net gain of 38 ATP (energy) and produce H20 and CO2 as byproducts.

You can have anaerobic respiration and aerobic respiration. The ultimate result is ATP. Anaerobic is done without oxygen (fermentation) and aerobic is done with oxygen,\n\nit starts with glycolosis which takes place in the cytoplasm. Glucose is turned into two pyruvates through a 10 reaction process meditated my enzymes. you produce one ATP and one NADH\n\nthen the pyruvates go into Krebs Cycle or the TriCarboxylic Acid Cycle and goes into the mitochondria. The pyruvate must be converted to acetyl Coenzyme A. then the acetyl Co A enters Krebs and continuously generates Oxaloacetate among other enery-rich compounds such as ATP, NADH and FADH2 with CO2\n\nthen final process is in the electron transport chain which takes place in the inner membrane if the mitochondria. In this process lots of H+ is pumped out of the membrane, which means that H+ is accumalated outside the inner matrix. then the concentration gradient causes a sudden influx of H+ back into the inner membrane which creates "proton-motive force" which zaps ADP+Pi= ATP. \n\nthe end result is 38 ATP for regular cells or 36 ATP for muscles and brain cells.\n\nOXYGEN IS REQUIRED!!! \n\nhope that helps\n\n*oh and ATP is a form of energy for the cell...

Fermentation yields 2 molecules of ATP. Before fermentation can take place another process: glycolysis happen; the 2 molecules of ATP are actually produced during glycolysis and are carried on through fermentation.\nThere are two types of fermentation: alcoholic fermentation in plants producing alcohol and lactic aacid fermentation in animals including humans, producing lactic acid. We go into lactic acid fermentation when we over exercise or exercise strenuously. It happens because of a lack of oxygen making the production of ATP needed for normal muscular contraction impossible. Lactic acid produces the feeling of muscle soreness.

Adenosine Triphosphate, or ATP as it is commonly known, is the cells currency for providing energy. ATP is made in the mitochondria via respiration (more precisely oxidative phosphorylation). This process involves the addition of a phosphate group to a pre-existing adenosine diphosphate group. The ATP is then transported out of the mitochondria and transported around the cell to where reactions occur that require energy input.At these sites ATP is hydrolysed (water added) to form ADP (ATP +  H20 = ADP + P + Energy). The energy is provided in the form of heat energy which is usually used in catabolic reactions to break bonds.

I think (only think) it's because pyruvate (a product of glycolysis) is able to cross the internal membrane thus allowing ATP production with carbon dioxide as a by-product, whilst glucose is unable to do so.\nI would read my two references to check.\nGood luck.

Aerobic respiration requires oxygen in order to generate energy. It is the preferred method of pyruvate breakdown from glycolysis and requires that pyruvate enter the mitochondrion to be fully oxidized by the Krebs cycle. The product of this process is energy in the form of ATP (Adenosine Triphosphate), by substrate-level phosphorylation, NADH and FADH2. The reducing potential of NADH and FADH2 is converted to more ATP via an electron transport chain with oxygen as the "terminal electron acceptor". Most of the ATP produced by cellular respiration is by oxidative phosphorylation, ATP molecules are made due to the chemiosmotic potential driving ATP synthase. Respiration is the process by which cells obtain energy when oxygen is present in the cell.\n\nTheoretically, 36 ATP molecules can be made per glucose during cellular respiration, however, such conditions are generally not realized due to such losses as the cost of moving pyruvate into mitochondria. Aerobic metabolism is rather more efficient than anaerobic metabolism. They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and at the cell membrane in prokaryotic cells.\n\nGlycolysis\nMain article: Glycolysis \nGlycolysis is a metabolic pathway that is found in all living organisms and does not require oxygen. The process converts one molecule of glucose into two molecules of pyruvate, and makes energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced but two are consumed for the preparatory phase. The initial phosphorylation of glucose is required to destablise the molecule for cleavage into two triose sugars. During the pay-off phase of glycolysis four phosphate groups are transfered to ADP by substrate-level phosphorylation to make four ATP and two NADH are produced when the triose sugars are oxidised. Glycolysis takes place in the cytoplasm of the cell. The overall reaction can be expressed this way:\n\nGlucose + 2 ATP + 2 NAD+ + 2 Pi + 4 ADP → 2 pyruvate + 2 ADP + 2 NADH + 4 ATP + 2 H2O + 4 H+ \n\nOxidative decarboxylation\nMain article: Oxidative decarboxylation \nProduces acetyl-CoA from pyruvate. This oxidation reaction also releases carbon dioxide as a product.\n\nKrebs cycle/Citric Acid cycle\nMain article: Citric acid cycle \nWhen oxygen is present, acetyl-CoA enters the citric acid cycle, and gets oxidised to CO2 while at the same time reducing NAD to NADH. NADH can be used by the electron transport chain to create further ATP as part of oxidative phosphorylation. To fully oxidise the equivalent of one glucose molecule two acetyl-CoA must be metabolised by the Krebs cycle. Two waste products, H2O and CO2 are created during this cycle, .\n\nOxidative phosphorylation\nMain articles: Oxidative phosphorylation , Electron transport chain , Electrochemical gradient, and ATP synthase\n\nIn eukaryotes, oxidative phosphorylation occurs in the mitochondria. It comprises of the electron transport chain that establishes a proton gradient (chemiosmotic potential) across the inner membrane by oxidising the NADH produced from the Krebs cycle. ATP is synthesised by the ATP synthase enzyme when the chemiosmotic gradient is used to drive the phosphorylation of ADP.\n\nTheoretical yields\nThe yields in the table below are for one glucose and molecule being fully oxidised to carbon dioxide. It is assumed that all the reduced coenzymes are oxidised by the electron transport chain and used for oxidative phosphorylation.
