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)

To form NADPH from NADP+, the necessary reactants are **two electrons and one hydrogen ion**. This means the correct option would be **two electrons and two hydrogen ions**. However, NADPH contains one of the hydrogen atoms within the molecular structure, which is why it effectively becomes neutral after accepting the electrons and one hydrogen ion.

Thus, the response you should select is **two electrons and two hydrogen ions**.
