Question

Quizplus · Accepted Answer

All of the choices- Acetyl-CoA, TCA cycle intermediates, and glycolysis intermediates can provide carbon skeletons for the synthesis of amino acids. Acetyl-CoA can be converted to citrate in the TCA cycle, which can then provide oxaloacetate and α-ketoglutarate. Glycolysis intermediates can also be converted to pyruvate, which can provide both alanine and non-essential amino acids, such as serine and cysteine.
