When oxygen is present, the mitochondria will undergo aerobic respiration which leads to the Krebs cycle. However, if oxygen is not present, fermentation of the pyruvate molecule will occur.
No. The first stage of cellular respiration, Glycolysis, does not require oxygen and produces a net of two (2) ATP molecules per molecule of glucose. If you run a lot, you may feel a bit painful in the legs.* This is partially due to the lack of oxygen entering your blood. However, your leg cells still need ATP to maintain the action of running.
