In the absence of oxygen, glycolysis allows cells to make small amounts of ATP through a process of fermentation. none Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.In glycolysis, glucose is split into two molecules of pyruvate.This results in a net gain of two ATP molecules. The lactic acid produced is the “burn” that athletes feel after an intense workout. Oxygen plays a key role as it increases ATP production from 4 ATP molecules to about 30 ATP molecules. In cellular respiration, CO 2 and H 2 O are produced along with the energy. It is done by yeast and some strains of bacteria. The incomplete anaerobic oxidation of one molecule of glucose yields a net gain of only 2 ATP because in the absence of oxygen the TCA cycle halts due to a deficit of the acceptor — oxygen — of the electrons from NADH and FADH 2. Already a member? Another name for fermentation is anaerobic respiration because the process is done in the absence of oxygen (“an” = not, “aero” = air or atmosphere). because all of the available energy remains in either lactate or ethanol two ATPd.
