Multiple Choice
Which of the following statements is NOT true about metabolism?
A
Anabolism is the breakdown of complex molecules into simpler ones.
B
Metabolic pathways are sequences of enzymatically catalyzed chemical reactions.
C
Metabolism includes all chemical reactions that occur within an organism.
D
Catabolism releases energy by breaking down complex molecules.
Verified step by step guidance1
Begin by understanding the definitions of key terms related to metabolism: Anabolism and Catabolism.
Anabolism refers to the process of building up complex molecules from simpler ones, which requires energy. It is the opposite of what is stated in the incorrect statement.
Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. This aligns with the correct statement about catabolism.
Metabolic pathways are indeed sequences of enzymatically catalyzed chemical reactions, which is a true statement.
Metabolism encompasses all chemical reactions within an organism, including both anabolic and catabolic processes, making this statement true.
