The electrons lost from the reaction center of photosystem I are replaced by electrons from A) CO₂. B) H₂O. C) ATP. D) photosystem II.

Question

Quizplus · Accepted Answer

The electrons lost from the reaction center of photosystem I are replaced by electrons from photosystem II during the process of photosynthesis. This process is known as the electron transport chain, where the excited electrons produced in photosystem II are transported to photosystem I through a series of electron carriers. The electrons lost by photosystem I are then replaced by the electrons received from photosystem II. Thus, option D is the correct choice.
