Detailed explanation-1: -Aerobic respiration generates 38 ATP, while anaerobic respiration generates 2 ATP using one glucose molecule. Anaerobic respiration thus produces less energy than aerobic respiration.

Detailed explanation-2: -Anaerobic respiration releases less energy than aerobic respiration but it does this more quickly. The product of this reaction is lactic acid. This builds up in muscles causing pain and tiredness, which can lead to cramp.

Detailed explanation-3: -Glucose is not completely broken down, so less energy is released than during aerobic respiration.

Detailed explanation-4: -Anaerobic respiration leads to an incomplete breakdown of glucose. It releases around 5% of the energy released by aerobic respiration per molecule of glucose. Clearly, the release of energy in the aerobic process is a lot more than in an anaerobic process.

Detailed explanation-5: -Anaerobic respiration produces less energy because: Incomplete breakdown of the respiratory substrate takes place. Some of the products of anaerobic respiration can be oxidized further to release energy which shows that anaerobic respiration does not liberate the whole energy contained in the respiratory substrate.
