If the inner mitochondrial membrane were to become permeable to protons, what would be the MOST immediate consequence on ATP synthesis?
ATP synthesis would increase due to increased proton flow.
ATP synthesis would stop because the proton gradient would dissipate.
ATP synthesis would be unaffected as it relies on substrate-level phosphorylation.
ATP synthesis would decrease, but some ATP would still be produced by glycolysis.
