SUMMARY
Probably the most striking similarity between the processes of cellular respiration and photosynthesis is that their overall reactions are basically the reverse of each other. The reactants in aerobic respiration are the products in photosynthesis, and vice versa.

Both processes produce ATP by chemiosmosis, and both have similar electron transfer compounds: NAD⁺ in aerobic respiration and NADP⁺ in photosynthesis. Both processes are associated with cell organelles surrounded by a double membrane—the mitochondrion in aerobic respiration and the chloroplast in photosynthesis.
