Questions and Answers

What is the primary distinguishing characteristic of anaerobic respiration?

  • It occurs in the presence of oxygen.
  • It produces a large amount of ATP.
  • It does not involve an electron transport chain.
  • It uses an electron acceptor other than oxygen. (correct)

Why does anaerobic respiration produce less ATP than aerobic respiration?

  • It uses a different type of glucose molecule.
  • It does not involve an electron transport chain.
  • The electron acceptor used is less efficient. (correct)
  • It is a much slower process.

What is the role of the electron transport chain in anaerobic respiration?

  • It is used to transport electrons to oxygen.
  • It is used to generate ATP directly.
  • It is used to transport electrons to an alternative electron acceptor. (correct)
  • It is not involved in anaerobic respiration.

Study Notes

Anaerobic Respiration

  • Anaerobic respiration occurs when oxygen isn't present for the cell.
  • It produces significantly less ATP compared to aerobic respiration.
  • It uses electron acceptors other than oxygen (O2).
  • Despite not using oxygen as the final electron acceptor, it still employs a respiratory electron transport chain.
