22. Where anaerobic respiration does takes place in human body? How does it led to fatigue and
muscle cramps?
Answers
Answer:
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.[1]
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is Oxygen. Molecular Oxygen is a highly oxidizing agent and, therefore, is an excellent electron acceptor. In anaerobes, other less-oxidizing substances such as Nitrate (NO3−), Fumarate, Sulphate (SO42−), or Sulphur (S) are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Therefore, anaerobic respiration is less efficient than aerobic.
