Quizplus · Accepted Answer

The figure shows energy flowing from catabolism to ATP synthesis, which in turn powers cellular work. This suggests that ATP acts as an intermediate molecule that stores energy from catabolism and makes it available for cellular work. Choices A and D are incorrect because they suggest that energy from catabolism is used directly or moves directly between ATP and ADP, respectively. Choice B is incorrect because it refers to a set of molecules that are not shown or mentioned in the figure.
