Detailed explanation-1: -Aerobic respiration occurs in the presence of oxygen. It includes glycolysis, the conversion of pyruvate into acetyl CoA by pyruvate dehydrogenase, followed by subsequent yielding of carbon dioxide, NADH, FADH2, ATP by Krebs cycle and electron transport chain. Hence, the assertion is incorrect.
Detailed explanation-2: -Answer: (a) The statement is false. One mole of glucose in aerobic respiration yields 38 ATP.
Detailed explanation-3: -Answer: During anaerobic cellular respiration, glucose is broken down without oxygen. The chemical reaction transfers glucose energy to the cell. In fermentation, instead of carbon dioxide and water, lactic acid is produced which can lead to painful muscle cramps.
Detailed explanation-4: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.
