An Overview of Metabolism Is Shown in the Following Figure

An overview of metabolism is shown in the following figure. What does this figure tell us about the energy of catabolism and anabolism?

A) Anabolic reactions occur more quickly than catabolic reactions.
B) Catabolism is exothermic and anabolism is endothermic.
C) Overall, we exert more energy than we consume.
D) Overall, the amount of energy that goes into anabolic processes is the same as is released in catabolic processes.
E) The conservation of energy does not apply to biological systems.
