How many ATP are produced per 1 molecule of glucose in cellular respiration? If cellular respiration occurs in the presence of oxygen, then there is a net gain of 36 ATP molecules.
1) Glucose Produces Two Pyruvic Acid Molecules: Glucose with 6 carbons is split into two molecules of 3 carbons each at Step 4. As a result, Steps 5 through 10 are carried out twice per glucose molecule. Two pyruvic acid molecules are the end product of glycolysis per mono- saccharide molecule. ATP is required at Steps 1 and 3.
