Reaction pathways that transform fuels into cellular energy are: 
A) anabolic.

D) All of the above.
E) None of the above.

Quizplus · Accepted Answer

The catabolic pathway is the process of breaking down molecules into smaller units to release energy. This is the process by which fuels are transformed into cellular energy, so the correct choice is B: catabolic. Anabolic pathways are the opposite, they are processes that build larger molecules from smaller ones using energy, and ametabolic pathways do not involve any metabolic processes at all. Therefore, choices A and C are incorrect.
