Questions and Answers

What is the primary function of the first stage in energy generation from food?

  • To break down large molecules into smaller units (correct)
  • To produce ATP
  • To hydrolyze fatty acids
  • To degrade small molecules

Which molecules play a central role in metabolism in the second stage of energy generation from food?

  • Sugars, fatty acids, glycerol, and several amino acids (correct)
  • Glucose and polysaccharides
  • Proteins and glycerol
  • Acetyl CoA and ATP

What is the function of acetyl CoA in the third stage of energy generation from food?
