ANATOMY

Detailed explanation-1: -The end products of anaerobic respiration vary, such as gases, alcohols, acids, and energy. In fermentation, only 2 ATPs are produced. Also, there is incomplete oxidation of carbohydrates. It occurs in simple prokaryotes, yeasts, and the muscle cells of humans during intense exercise.

Detailed explanation-2: -Anaerobic respiration produces energy much quicker than aerobic respiration but only produces 1/20th as much. Lactic acid is also produced, and this can build up in muscles causing pain, fatigue and an oxygen debt.

Detailed explanation-3: -Lactic Acid: A byproduct of anaerobic respiration which strongly contributes to muscle fatigue.

Detailed explanation-4: -Anaerobic respiration takes place in human muscle cells, where the breakdown of glucose produces lactic acid and energy.
