Question

Which statement is false about ATP synthase?

A) ATP synthase is a complex enzyme.
B) ATP synthase is located in the mitochondria.
C) ATP synthase synthesizes ATP from ADP and inorganic phosphate.
D) ATP synthase functions in cellular respiration but not in photosynthesis.

Answer 1

The false statement about ATP synthase is that it functions in cellular respiration but not in photosynthesis, whereas it actually functions in both processes.

Step-by-step explanation:

The statement that is false about ATP synthase is: D) ATP synthase functions in cellular respiration but not in photosynthesis. In fact, ATP synthase plays a crucial role in both cellular respiration and photosynthesis. During cellular respiration, it is located in the mitochondria where it creates ATP by using a proton gradient across the inner mitochondrial membrane created by the electron transport chain. Meanwhile, in photosynthesis, ATP synthase is found in the thylakoid membranes of chloroplasts and synthesizes ATP during the light-dependent reactions. Thus, the correct answer is that ATP synthase does indeed function in both cellular respiration and photosynthesis.
