A) The electron carriers involved in photophosphorylation are located on the thylakoid membranes
B) Photosynthesis is a redox process, in which water is oxidized and carbon dioxide is reduced
C) The enzymes required for carbon fixation are located only in the grana of chloroplasts
D) In green plants, both PS-I and PS-II are required for the formation of NADPH ${+ H}^{+}$
Explanation
