During the process of Photosystem I, NADP+ is changed into NADPH. NADPH has a neutral charge. What reactants are necessary to form the product?(1 point)

The correct response is:

**two electrons and a hydrogen ion.**

In the process of Photosystem I, NADP+ is reduced to NADPH, which requires two electrons and one hydrogen ion (H⁺) to complete the reduction process. The overall reaction can be summarized as:

\[ \text{NADP}^+ + 2e^- + H^+ \rightarrow \text{NADPH} \]

This indicates that two electrons and one hydrogen ion are involved in the formation of NADPH from NADP+.
