Questions and Answers

What is the main purpose of gluconeogenesis?

  • To convert glucose into glycogen
  • To store excess glucose in the liver
  • To break down glucose into energy
  • To generate glucose from non-carbohydrate carbon substrates (correct)

    • In which organisms does gluconeogenesis occur?

  • Only in plants
  • Only in animals
  • All animals, plants, fungi, and microbes (correct)
  • Only in fungi

    • What is the energy cost of producing glucose through gluconeogenesis?

  • $2 pyruvate + 4 ATP + 2 GTP + 2 NADH \rightarrow glucose + 4 ADP + 2 GDP + 2 NAD+ + 6 Pi$ (correct)
  • $2 pyruvate + 2 ATP + 2 GTP + 2 NADH \rightarrow glucose + 2 ADP + 2 GDP + 2 NAD+ + 6 Pi$
