Answer:
e. both involve oxidation and reduction reactions
Explanation:
During photosynthesis, light-dependent reactions from NADPH by reduction of NADP. Oxidation of water molecules releases molecular oxygen as a by-product. The light-independent phase of photosynthesis reduces CO2 into organic nutrients such as glucose. The NADPH formed during light reaction donate electrons for these reduction reactions.
Glycolysis and Kreb's cycle together oxidize glucose molecules into CO2 and H2O. The released electrons are accepted by NAD and FAD and the NADH and FADH2 are formed. ETC of cellular respiration includes oxidation of NADH and FADH2 while the molecular oxygen is reduced.
