Question

One example of a stage 2 reaction in the heterotrophic breakdown of food molecules is:

  1. the extracellular digestion of amylopectin into glucose monomers
  2. the intramitochondrial digestion of fatty acids into carbon dioxide and water
  3. the intracellular digestion of glucose monomers into pyruvate
  4. the extracellular digestion of triglycerides into fatty acids and glycerol
  5. the extracellular digestion of polypeptides into amino acids

 

Identify the three-carbon glycolysis intermediate which can be formed, in the cytoplasm, in one enzymatic step (during deamination of the amino acid alanine)?

  1. pyruvate
  2. fructose-1,6-bisphosphate
  3. fructose
  4. glucose-6-phosphate
  5. glucose
