Why is anaerobic respiration considered less efficient than aerobic respiration? A Less energy is required during anaerobic respiration than aerobic respiration. B More oxygen is required for anaerobic respiration than for aerobic respiration. C More ATP molecules are gained in aerobic respiration than in anaerobic respiration. D Less lactic acid is formed during anaerobic respiration than during aerobic respiration.

A

Explanation:

A Less energy is required during anaerobic respiration than aerobic respiration

The correct answer is C More ATP molecules are gained in aerobic respiration

Explanation:

Aerobic respiration is named so bacause it occurs in presence of oxygen. Aerobic respiration consist of Glycolysis, TCA cycle and Oxidative phosphorylation. These 3 process additionally leads to the formation of 38 molecules of ATP. 1 ATP molecule can generate - 30.5kj/mole energy. As a result ATP is considered is the energy currency of the cell. ATP is used to carry out different process such as Active transport, Muscle contraction etc.

On the other hand Anaerobic respiration generates only 2 Moleclues of ATP. These 2 molecules are generated by the conversion of 1,3 bisphosphoglycerate to 3 Phosphoglycerate by substrate Lebel phosphorylation.
