A) Energy from catabolism can be used directly for performing cellular work.
B) ADP + ᵢ are a set of molecules that store energy for catabolism.
C) ATP is a molecule that acts as an intermediary to store energy for cellular work.
D) ᵢ acts as a shuttle molecule to move energy from ATP to ADP.

Quizplus · Accepted Answer

The figure shows a cycle where ATP is broken down into ADP and Pi to release energy, which is then used for cellular work. The arrow from catabolism to ATP synthesis shows that energy from catabolism is used to regenerate ATP. Therefore, ATP is a molecule that acts as an intermediary to store energy for cellular work. Option A is incorrect because catabolism releases energy, which is used to generate ATP, not for direct cellular work. Option B is incorrect because the molecules mentioned are not known to store energy for catabolism. Option D is incorrect because there is no shuttle molecule mentioned in the figure.
