Current Question (ID: 11362)

Question:

Which of the following statement is incorrect?

Options:

1. Electrons to PS-I are provided by PS-II
2. Electrons to PS-II are provided by the splitting of water
3. Electrons to PS-I are provided by the splitting of water
4. PS-II is physically located on the inner side of the membrane of the thylakoid.

Solution:

Electrons to PS-I are not provided by the splitting of water. PS-I receives electrons from the electron carrier plastocyanin, which in turn receives them from the electron transport chain between PS-II and PS-I. The electrons that are ultimately used to reduce NADP⁺ to NADPH are provided by PS-I, but they come from plastocyanin, not water. The electrons for the reduction of the primary electron acceptor of PS-II come from the splitting of water, which occurs in PS-II. PS-II is physically located on the thylakoid membrane on the side facing the lumen or inner space of the thylakoid.
