In photosynthetic ETS 4H+ ion are needed to produce 1 ATP, While in respiratory ETS 2H+ ion are required to produce 1 ATP. as in both case enzyme is ATPase then why there is difference in no. of H+ ion utilisation?
The amount of H+ ions required to synthesise ATP molecules depends on the electron acceptors present in the electron transport chain.
In photosynthesis, there are several electron acceptors as compared to respiration. This results in a variation in the quantum of H+ ions generated.
