Which of the Following Statements is True

Question

Which of the following statements is true?
A) Catabolic reactions are synthesis reactions.
B) Anabolic reactions are involved in the production of proteins from amino acids.
C) The energy derived from anabolism is used to drive catabolism.
D) Anabolic reactions release energy.
E) Catabolic reactions consume energy.

Accepted Answer

Anabolic reactions involve the synthesis of larger molecules from smaller ones, such as the production of proteins from amino acids. Catabolic reactions, on the other hand, involve the breakdown of larger molecules into smaller ones to release energy. Option A is incorrect because catabolic reactions are not synthesis reactions, but rather, they are degradation reactions. Option C is incorrect because anabolism requires energy input, while catabolism releases energy. Option D is incorrect because anabolic reactions require energy input for the synthesis of larger molecules. Option E is incorrect because catabolic reactions release energy, rather than consume it.
