No matter what substrate is used to fuel electron transport, only two entry points into the electron transport system are known to be used by mitochondria. This last step in electron transport serves the critical function of removing electrons from the system so that electron transport can operate continuously

Aerobic Respiration This process takes place in specialized structures within the cell called mitochondria, and uses the products of glycolysis, the pyruvate molecules, to release energy, along with CO2 and water as the by-products of the reaction. While photosynthesis is performed by most plants who can prepare their own food, most animals fulfill their energy requirements through cellular respiration

Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP.In respiration, glucose is oxidized and thus releases energy. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.To regenerate NAD+ from NADH, the electrons from NADH are added to pyruvate to produce alcohol (plants, yeast) or lactate (animals, bacteria).The total ATP yield of fermentation comes from glycolysis; 2 ATP molecules are produced per glucose

Thus, during short bursts of strenuous activity, muscle cells use anaerobic respiration to supplement the ATP production from the slower aerobic respiration, so anaerobic respiration may be used by a cell even before the oxygen levels are depleted, as is the case in sports that do not require athletes to pace themselves, such as sprinting
