Answer;
ATP would not be produced by oxidative phosphorylation.
If the inner mitochondrial membrane were freely permeable to h+, ATP production by ATP synthase through oxidative phosphorylation would not occur.
Step-by-step explanation;
-Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers.This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms.
-Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.
-Therefore; If the inner mitochondrial membrane were freely permeable to h+, ATP production by ATP synthase through oxidative phosphorylation would not occur.
