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)

Question

• an electron and two hydrogen ions
• two electrons and a hydrogen ion
• an electron and a hydrogen ion
• two electrons and two hydrogen ions

Answer 1

To form NADPH from NADP+, the correct reactants needed are two electrons and one hydrogen ion. However, since this specific option is not among your choices, the best match from your options would be:

• two electrons and a hydrogen ion

Keep in mind that while NADPH formation includes transferring two electrons and one hydrogen ion, the total charge balance is achieved as it ultimately reacts with a second hydrogen ion (proton) in the overall metabolic context.
