Detailed explanation-1: -Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.

Detailed explanation-2: -Anaerobic respiration in muscle produces Lactic Acid and Energy. It does not produce carbon dioxide, hence the correct answer is 2.

Detailed explanation-3: -The products of anaerobic respiration are lactic acid, carbon dioxide, and water. Anaerobic respiration is the breakdown of glucose in the absence of oxygen. Inside the cell cytoplasm, glucose breaks down into pyruvic acid. If oxygen is absent, then pyruvic acid converts into lactic acid, carbon dioxide, and water.

Detailed explanation-4: -During anaerobic respiration, the oxidation of glucose is incomplete-not all of the energy can be released from the glucose molecule as it is only partially broken down. glucose → lactic acid (+ ATP made) The lactic acid is a waste product. glucose → ethanol + carbon dioxide (+ ATP made) More items
