Which of the Following is an Example of Catabolism

Question

Which of the following is an example of catabolism?
A)The assembly of the cell membrane from precursor molecules
B)The increase in muscle tissue with exercise
C)The formation of secretory proteins in the pancreas
D)The breakdown of glucose in the cytoplasm and mitochondria

Accepted Answer

Catabolism refers to the breakdown of complex molecules into simpler ones, releasing energy in the process. The breakdown of glucose in the cytoplasm and mitochondria is an example of catabolism. The assembly of the cell membrane from precursor molecules, the increase in muscle tissue with exercise, and the formation of secretory proteins in the pancreas are all examples of anabolism, which involves the synthesis of complex molecules from simpler ones, requiring energy.
