The process of converting excess amino acids into glucose is called

  • A Gluconeogenesis from pyruvate generated solely during anaerobic glycolysis
  • B Glycogenolysis, the breakdown of stored liver glycogen into free glucose
  • C Transamination, the transfer of an amino group between two keto acids
  • D Deamination followed by gluconeogenesis

Correct answer: D. Deamination followed by gluconeogenesis

Explanation: Amino acids are first deaminated (amino group removed as urea) and then the carbon skeleton enters gluconeogenesis to form glucose. Both steps are needed.

Concept context

Carbohydrates, proteins, lipids, nucleic acids, and enzyme kinetics. Essential foundation for understanding metabolism.
