Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposed by Mitchell, explains the process of ATP formation and states that it is linked to development of a proton gradient across the mitochondrial membrane. ATP synthase, required for ATP synthesis is located in ${\mathrm{F}}_1$ particles present in the inner mitochondrial membrane and becomes active only when there is high concentration of proton on ${\mathrm{F}}_0$ side as compared to ${\mathrm{F}}_1$ side. The flow of proton through ${\mathrm{F}}_0$ channel induces ${\mathrm{F}}_1$ particle to function as ATP synthase and the energy of proton gradient produces ATP by attaching a phosphate radical to ADP.
