Question

.When an electron is removed from the reaction center of photosystem II, how

is the missing electron then replenished?

A. With an electron from a sunlight
B. With an electron from a hydrogen ion
C. With an electron removed from water
D. With an electron removed from photosystem I

Answer 1

The missing electron in the reaction center of photosystem II is replenished by an electron removed from water.

Step-by-step explanation:

The missing electron in the reaction center of photosystem II is replenished by an electron removed from water. During the process of photosynthesis, energy from sunlight is used to extract electrons from water in photosystem II. These electrons then travel through the chloroplast electron transport chain to photosystem I, which reduces NADP+ to NADPH. In photosystem II, splitting of water adds protons to the thylakoid lumen and releases oxygen as a waste product.
