Molecules Called Uncouplers Allow Protons to Cross the Inner Mitochondrial

question 13

Multiple Choice

Molecules called uncouplers allow protons to cross the inner mitochondrial membrane.What effect would this have on ATP production in the mitochondria?

• A) ATP production would not change, because protons cross the outer mitochondrial membrane to produce ATP.
• B) ATP production would increase, because this would spontaneously establish a proton gradient, for powering ATP synthase.
• C) ATP production would increase, because this would make more oxygen available in the mitochondrial matrix.
• D) ATP production would decrease, because electrons would not be able to move through the electron transport chain.
• E) ATP production would decrease, because the proton gradient, for powering ATP synthase, would dissipate.
