Detailed explanation-1: -Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

Detailed explanation-2: -Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6-> 2C3H6O3 (Glucose-> Lactic acid).

Detailed explanation-3: -Lactic acid is the byproduct of anaerobic respiration in animals. Without molecule oxygen, anaerobic respiration occurs in animal muscle cells.

Detailed explanation-4: -The majority of plants and animals, including birds, humans and other mammals, use aerobic respiration. Anaerobic respiration is used by microscopic organisms such as bacteria and fungus.
