Fatty Acids Must First Be Converted to Which Substance Before

Question

Fatty acids must first be converted to which substance before they can enter the citric acid cycle?  
A) PGAL
B) pyruvate
C) acetyl-CoA
D) amino acids
E) glucose

Accepted Answer

Fatty acids are broken down into two-carbon units by beta oxidation, which are then combined with Coenzyme A to form acetyl-CoA. Acetyl-CoA enters the citric acid cycle and is oxidized to produce ATP energy. Therefore, option C is the correct answer.
