Ketone bodies, acetyl-CoA, and glucose are three metabolites that result from the breakdown of the carbon skeleton of amino acids. Determine which of these metabolites are produced by ketogenic amino acids and which by glucogenic amino acids.

• A. Ketogenic amino acids produce acetyl-CoA and ketone bodies, while glucogenic amino acids produce glucose.
• B. Ketogenic amino acids produce glucose, while glucogenic amino acids produce acetyl-CoA and ketone bodies.
• C. Both ketogenic and glucogenic amino acids produce only acetyl-CoA.
• D. Both ketogenic and glucogenic amino acids produce only glucose.

Answer: (A)
