Which of the following statements most accurately compares photosynthesis and respiration?
A)ATP generated during photosynthesis is a fundamentally different process than ATP generated during respiration.
B)Photosynthesis is just respiration in reverse.
C)Photosynthesis requires ATP,but respiration does not.
D)Photosynthesis stores energy in complex organic molecules;respiration releases the energy stored in complex organic molecules.

Question

Quizplus · Accepted Answer

Photosynthesis is the process of storing energy in complex organic molecules such as glucose, while respiration is the process of releasing that stored energy in the form of ATP. Therefore, option D is the most accurate comparison of the two processes. Option A is incorrect because ATP generation in both processes is through the same mechanism of electron transport chain. Option B is incorrect because although they have opposite reactions, they are not the same process. Option C is incorrect because both photosynthesis and respiration require ATP, although the source of ATP is different.
