Detailed explanation-1: -Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
Detailed explanation-2: -The final end products of cellular respiration are ATP and H2O. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH, and two H2O.
Detailed explanation-3: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
Detailed explanation-4: -Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Unlike aerobic respiration, the end products here are ethyl alcohol as in yeasts and lactic acid as in animal cells. So the answer is ‘Alcohol and lactic acid’.
Detailed explanation-5: -ATP is hydrolyzed to ADP in the reaction ATP+H2O
