What is the difference between photophosphorylation and oxidative phosphorylation?
Photophosphorylation:
Photophosphorylation is the mechanism by which the ATP molecule is formed from ADP and inorganic phosphate utilizing the energy absorbed from the sun during photosynthesis in plants.
Oxidative phosphorylation:
It is the method by which ATP is produced in mitochondria using electrons transported from the electron transport chain.

2. Light energy is used in photophosphorylation to generate a proton gradient | 2. Proton gradient is generated by Electron transport system(ETS), ETS gets electrons from the oxidation of NADH and FADH2. |
3. Protons accumulate in the lumen of the chloroplast during photophosphorylation | 3. Protons accumulate in the intermembranous region of mitochondria during oxidative phosphorylation. |
