Which describes the function of ATP synthase in light-dependent reactions of photosynthesis?
A. uses the energy from a proton gradient to synthesize ATP from ADP and phosphate
B. uses a proton gradient to transport glucose across the thylakoid membrane
C. converts light energy directly to ATP
Answer (2)
ATP synthase synthesizes ATP by using energy from a proton gradient during the light-dependent reactions of photosynthesis. This occurs as protons flow back across the thylakoid membrane due to the energy generated by light absorption. It is a crucial step in producing the energy necessary for cellular activities. ;
ATP synthase catalyzes the formation of ATP during light-dependent reactions of photosynthesis by utilizing energy from a proton gradient established across the thylakoid membrane. This process is known as chemiosmosis and is vital for storing energy in the form of ATP. The correct option is A: uses the energy from a proton gradient to synthesize ATP from ADP and phosphate.
