Explain how proteins can be metabolized by the same pathways that oxidize glucose. What will be an ideal response?
As shown in Fig. 8-13, proteins are converted to their component amino acids which in turn are
deaminated to urea and various types of carbon skeletons. These carbon skeletons then feed into
glycolysis, the citric acid cycle, and/or are converted to acetyl CoA.
