The intermediates of the citric acid cycle are constantly being depleted because they are used to produce many of the amino acids needed to make proteins.
 
  The enzyme pyruvate carboxylase converts pyruvate to oxaloacetate to replenish these intermediates. Bacteria, but not animal cells, have additional enzymes that can carry out the reaction acetyl CoA + isocitrate -> oxaloacetate + succinate. Which of the following compounds will not support the growth of animal cells when used as the major source of carbon in food, but will support the growth of nonphotosynthetic bacteria?
  (a) pyruvate
  (b) glucose
  (c) fatty acids
  (d) fructose
