Glycolysis is the first stage of cellular respiration producing atp. what is the net gain of atp molecules per molecule of glucose from glycolysis? a. 1 b. 2 c. 4 d. 36

cellular respiration uses energy in glucose to make ATP. 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.
