Answer 1

To form NADPH from NADP+, the reaction requires two electrons and one hydrogen ion (proton). Therefore, the correct response is:

two electrons and one hydrogen ion

However, since this option is not listed among your responses, the most closely related option would be:

two electrons and two hydrogen ions

This is because in the light-dependent reactions of photosynthesis, the electrons come from water and a proton is needed to form NADPH. The overall reaction effectively incorporates these species to produce NADPH from NADP+.
