Question 20

Which statement best compares the processes of anabolism and catabolism?

Accepted Answer

A)  Both catabolism and anabolism take place outside of the cells in the GI tract. 
B)  Catabolism breaks food molecules down into smaller molecular compounds and, in so doing, releases energy from them. Anabolism does the opposite. 
C)  Anabolism breaks food molecules down into smaller molecular compounds and, in so doing, releases energy from them. Catabolism does the opposite. 
D)  Anabolism occurs when nutrient molecules enter cells, undergo many chemical changes, and release ATP for energy; catabolism doesn't release ATP.
