how many net molecules of atp are produced from the complete oxidation of one molecule of glucose?
two
in anaerobic respiration, one glucose molecule produces a net gain of two atp molecules (four atp molecules are produced during glycolysis through substrate-level phosphorylation, but two are required by enzymes used during the process). in aerobic respiration, a molecule of glucose is much more profitable in that a maximum net production of 30 or 32 atp molecules (depending on the organism) through oxidative phosphorylation is generated.
glucose
glycolysis is a metabolic pathway that takes place in the cytosol of cells in all living organisms. this pathway can function with or without the presence of oxygen. in humans, aerobic conditions produce pyruvate and anaerobic conditions produce lactate. in aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of atp. four molecules of atp per glucose are actually produced, however, two are consumed as part of the preparatory phase. the initial phosphorylation of glucose is required to increase the reactivity (decrease its stability) in order for the molecule to be cleaved into two pyruvate molecules by the enzyme aldolase. during the pay-off phase of glycolysis, four phosphate groups are transferred to adp by substrate-level phosphorylation to make four atp, and two nadh are produced when the pyruvate are oxidized. the overall reaction can be expressed this way:
