Example Questions

Example Question #1 : Ethanol Fermentation

Multiple studies have shown that drinking lots of alcohol can lead to an increase in body fat. 

From a biochemical perspective, what aspect of alcohol metabolism may suggest that it contributes to an increase in body fat?

Possible Answers:

Production of acetyl-CoA

Formation of acetaldehyde

Formation of acetic acid

Formation of acetals and ketals 

Correct answer:

Production of acetyl-CoA

Explanation:

Fats are broken down into acetyl-CoA to be used for energy. However, large quantities of alcohol will produce large quantities of acetyl-CoA when metabolized. Acetyl-CoA can be converted into fatty acids when it is in excess. Then fatty acids can assemble into triglycerides and be stored as fat.
