Question

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.

Answer 1

A

Step-by-step explanation:

A Less energy is required during anaerobic respiration than aerobic respiration

Answer 2

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

Step-by-step 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.
