Chemicals called uncouplers can make membranes permeable to small molecules and ions. What effect might uncouplers have on photosynthesis?
A)increased ATP production because cyclic electron transport would increase
B)decreased ATP production because the proton gradient would increase
C)decreased ATP production because the proton gradient would decrease
D)decreased NADPH production because the proton gradient would increase
E)decreased NADPH production because the proton gradient would decrease

Question

Quizplus · Accepted Answer

Uncouplers cause the proton gradient across the thylakoid membrane to decrease, which would lead to a decrease in ATP production during photosynthesis.
