Question

Which photosystem's main function is to generate high-energy electrons for the synthesis of ATP?

a) Photosystem I
b) Photosystem II
c) Chlorophyll System
d) Phycobilisome System

Answer 1

b) Photosystem II. Photosystem II is the photosystem that generates high-energy electrons for the synthesis of ATP in photosynthesis.

Step-by-step explanation:

The photosystem that generates high-energy electrons for the synthesis of ATP is Photosystem II.

Photosystem II is responsible for the initial process of photosynthesis and is located in the thylakoid membrane of chloroplasts. When photons strike Photosystem II, the chlorophyll molecules in the photosystem absorb the light energy and pass it to special chlorophyll a molecules in the reaction center. These chlorophyll a molecules then excite electrons, which are passed to the primary electron acceptor. The energy from the excited electrons is used to split water molecules, generating high-energy electrons that are used to create ATP through an electron transport chain.
