Pyruvic acid is a product of glycolysis .

The Electron Transport process is the third process in cell respiration, it requires oxygen directly. The electron transport "chain" is a series of electron carriers in the membrane of the mitochondria. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP (Adinosine triphosphate), an energy molecule is formed.Therefore this stage produces the most ATP.

Aerobic respiration is the discharge of energy from glucose or another organic substrate in the presence of OxygenThe three stages of aerobic respiration are glycolysis, citric acid cycle, and oxidative phosphorylation.Glycolysis takes place inside the cytoplasm; the citric acid cycle takes place inside the mitochondria, and the oxidative phosphorylation takes places in the mitochondria.Cellular respiration is in three stages as follows:GLYCOLYSISTakes place in the cytoplasm of the cell and is common to both aerobic and anaerobic respiration.glycolysis means literally that glucose is split and the 6 carbon glucose molecule is broken down to 2 X 3carbon molecules of Pyruvic acid. This produces a net gain of 2 ATP molecules.If oxygen is absent (anaerobic) in animal cells, such as muscle, 3C Pyruvic acid is converted to lactic acid.In plant cells, such as yeast, pyruvic acid is converted to 2C Ethanol + CO2 (fermentation)In both of the above only 2 ATP molecules are produced per glucose molecule respired.If oxygen is present (aerobic), pyruvic acid enters the mitochondrion to the fluid matrix where Kreb's cycle stages occur.During Kreb's cycle Citric acid is initially formed and is then broken down in a series of enzyme controlled rections releasing CO2 (waste product) and hydrogen.Hydrogen is picked up by a hydrogen carrier molecule called NAD and transported to the hydrogen carrier sytem (Cytochrome sytem) on the cristae of the mitochondrion for the final stage of respiration.Cytochrome system- electron transport system:Hydrogen is passed along a chain of hydrogen carrier molecules by a series of oxidation and reduction reactions.each time a hydrogen molecule is passed along, a molecule of ATP is produced from ADP and phosphate.The final Hydrogen acceptor is oxygen and produces a molecule of water (the other waste product).In all, 36 ATP molecules are generated during the Cytochrome system, making a total of 38 ATP (36 from cytochrome system + 2 ATP from glycolysis) produced when Glucose is respired aerobically.This makes aerobic respiration 19X more efficient at producing ATP than anaerobic respiration.Hope this helps!
1954 - when known as Footscray Bulldogs. That has been their ONLY grand final win.
Thhat they are dead meat! Lol!
No. That's ATP.
36 ATPs are produced.CO2 and H2O also given out.

NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
O2 ADDED: Not O2, but one atom of oxygen.
True, aerobic means that it needs oxygen. Oxidative respiration is cellular respiration with oxygen as the final acceptor at the end of the cycle.
Aerobic respiration is the type of cellular respiration that requires oxygen. This process involves the release of glucose for energy.Aerobic respiration requires oxygen to be present because it is the final electron acceptor at the end of the electron transport chain. If it is not present, then the electron can not go through the chain and fermentation will cycle instead. Fermentation is much more inefficient in producing ATP (a differenence of 32 ATP).
Oxygen is necessary for aerobic respiration only . It is not required in anaerobic respiration . Oxygen is final electron acceptor and it forms water at end of E.T.C.
Aerobic respiration ends in mitochondria. Anaerobic in the cytoplasm
Cellular respiration requires both glucose and oxygen. Glucose provides the energy for the cell and oxygen is required to be the final electron acceptor so that aerobic respiration can happen. Other molecules can enter cellular respiration and be broken down, but glucose is considered the start of this process. Oxygen is also not required, but if it is not present, then fermentation will run and this process is not nearly as efficient as aerobic respiration.
