Answer;
-34 ATP molecules.
Step-by-step explanation;
-Cellular respiration uses energy in glucose to make ATP. Aerobic (in presence of oxygen) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
-38 ATP molecules can be made per oxidized glucose molecule during cellular respiration that is; 2 ATP molecules from glycolysis, 2 ATP from the Krebs cycle, and about 34 ATP from the electron transport system.
