NAD(P)H and FAD(P)H are both an electron carrier produced in cellular respiration and photosynthesis. This two electron carriers then will enter electron chain transport and transfer their electrons to the next electron acceptor until the electrons reach oxygen. These electrons movement will pump H+ (proton) from one compartment to another. In cellular respiration, the electrons movement will cause proton to accumulate in the compartment between the inner and outer membrane of mitochondria. In photosynthesis, the electron movement will cause proton to accumulate inside the inter-thylakoid membrane. Accumulation of proton will create Proton Motive Force. PMF is then used by ATP synthase to create ATP, as the immediate movement of protons back
