Questions and Answers

In anaerobic cellular respiration, what are the two products of glucose breakdown?

  • Lactic acid and carbon dioxide (correct)
  • Ethanol and ATP
  • Carbon dioxide and ethanol
  • Lactic acid and ATP

Which of the following is NOT a characteristic of anaerobic cellular respiration?

  • It results in the formation of lactic acid.
  • It requires the presence of sunlight. (correct)
  • It occurs in the absence of oxygen.
  • It produces a relatively small amount of ATP.

What is the main difference between anaerobic cellular respiration and fermentation?

  • Anaerobic cellular respiration uses oxygen, while fermentation does not.
  • Anaerobic cellular respiration produces carbon dioxide, while fermentation does not.
  • Anaerobic cellular respiration produces lactic acid, while fermentation produces ethanol. (correct)

Study Notes

Anaerobic Respiration

  • Two main types: anaerobic cellular respiration and fermentation
  • Anaerobic cellular respiration produces lactic acid as a byproduct, along with a small amount of ATP
  • The process converts glucose to lactic acid, generating only 2 ATP.
  • Fermentation is a separate anaerobic process, and is different from anaerobic cellular respiration.
  • During strenuous exercise, insufficient oxygen limits aerobic respiration.
  • Consequently, anaerobic respiration steps in to produce ATP.
  • Anaerobic respiration converts glucose into lactic acid.
