Unformatted text preview: energy of the products is still lower than the some total energy of the reactants even if one of the molecules is gaining some energy. 3. Photosynthesis uses an electron carrier whose two forms are NADP + and NADPH. Light energy is stored by forming NADPH. a. Explain using three different observations if the NADPH form is reduced or oxidized. NAPPH is reduced. Molecules gaining hydrogens tend to be reduced and NADPH has gained a hydrogen as compared to NADP+. Hydrogen carry electrons with them, and a gain of electrons is a reduction reaction (GER/RIG). Reduction reactions tend to increase potential energy, and here we have stated that light energy is stored which would cause an increase in potential energy. b. Is NADP + an electron acceptor or is it an electron donor? NADPH? NADP+ is an acceptor and NADPH would act later as an electron donor....
