The Breakdown of ____ Yields Acetyl-CoA and Carbon Dioxide

Question

The breakdown of ____ yields acetyl-CoA and carbon dioxide.  
A) phosphoglycerate
B) pyruvate
C) oxaloacetate
D) PGAL
E) fructose bisphosphate

Accepted Answer

The breakdown of pyruvate yields acetyl-CoA and carbon dioxide. Pyruvate is the end product of glycolysis and is converted to acetyl-CoA in the presence of oxygen, which then enters the citric acid cycle. The other options listed do not directly yield acetyl-CoA and carbon dioxide.
