Detailed explanation-1: -The overall chemical reaction for cellular respiration is one molecule of glucose (C6H12O6) and six molecules of oxygen (O2) yields six molecules of carbon dioxide (CO2) and six molecules of water (H2O).
Detailed explanation-2: -Where is oxygen used in cellular respiration? In cellular respiration, oxygen is used in the inner mitochondrial membrane in the electron transport chain to facilitate oxidative phosphorylation.
Detailed explanation-3: -During aerobic respiration, one molecule of glucose is oxidized with the help of six oxygen molecules to produce six molecules of carbon dioxide. Six molecules of water are also produced in the process.
Detailed explanation-4: -It does not require oxygen. During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.
Detailed explanation-5: -So, the correct answer is 12 ATP.
