Answer:
Only Photosystem I - 1, 5, 6
Only photosystem II - 3, 2
Both Photosystem I and II - 4
Explanation:
Only Photosystem I
a) Reduction of NADP+ - uses light energy to convert NADP+ to NADPH2
b) Reduction of electron transport chain between the two photosystems
c) Oxidation of electron transport chain between the two photosystems.
Only photosystem II
a) Oxidation of water - here the absorbed light energy is used to dissociate of water molecules to produces protons (H+) and O2 along with free ions
b)Reduction of primary electron acceptor - An electron is taken by pheophytin which is a primary electron acceptor molecule that is located within photosystem II and hence it get reduced.
Both Photosystem I and II
a) Light is absorbed in both photosystem I and II. While in photosystem I, light waves of large wavelength i.e 700 nm are absorbed, in photosystem II light waves of short wavelength of i.e 680 nm are absorbed.
