In aerobic respiration, 36 or 38 molecules of ATP per molecule of glucose, depending on how many are gained through the electron transfer system.
In aerobic conditions, the processconverts one molecule of glucose into two molecules of pyruvate(pyruvic acid), generating energy in the form of two net molecules ofATP. Four molecules of ATP per glucose are actually produced;however, two are consumed as part of the preparatory phase. Theinitial phosphorylation of glucose is required to increase the reactivity(decrease its stability) in order for the molecule to be cleaved into twopyruvate molecules by the enzyme Aldolase.
