question 2 of 10
after electrons leave photosystem ii, they move through a chain of three protein complexes. where do they go after that electron transport chain?
a. photosystem i
b. photosystem ii
c. calvin cycle
d. photosystem iii

Explanation:

In the light - dependent reactions of photosynthesis, after electrons leave photosystem II and pass through the electron transport chain (which consists of three protein complexes: plastoquinone - cytochrome b6f - plastocyanin), they are transferred to photosystem I. Photosystem II is where electrons are initially excited and passed to the electron transport chain. The Calvin cycle is part of the light - independent reactions and does not directly receive electrons from this electron transport chain. There is no photosystem III in the standard photosynthetic electron transport process.

Answer:

A. Photosystem I
