Question

1. during the light dependent reaction of photosynthesis, p700’s electrons are replaced a. from photosystem ii b. from the splitting of carbon dioxide c. from nadph d. p700 never loses electrons e. none of these are correct

Explanation:

In the light - dependent reactions of photosynthesis, when P700 loses an electron, the electron is replaced by an electron from photosystem II. The splitting of carbon dioxide does not provide electrons for P700. NADPH is a product of the light - dependent reactions and not a source of electrons for P700. P700 does lose electrons during the process.

Answer:

A. from photosystem II
