Questions and Answers

What is the significance of glycolysis in erythrocytes?

  • Erythrocytes rely on glycolysis due to the lack of mitochondria. (correct)
  • Erythrocytes possess mitochondria for oxidative phosphorylation.
  • Erythrocytes convert pyruvate to lactate through the TCA cycle.
  • Erythrocytes perform glycolysis aerobically.

    • What is the role of glycolysis in providing ATP under anaerobic conditions?

  • Converts glucose to glycogen.
  • Generates ATP through oxidative phosphorylation.
  • Produces ATP in the absence of oxygen. (correct)
  • Forms acetyl-CoA for the TCA cycle.
