question 10

Multiple Choice

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

• B)decreased ATP,because protons would not be available to pass through the ATP synthase
• C)no effect,because protons cross the outer mitochondrial membrane to produce ATP
• D)increased ATP,because this would spontaneously establish a proton gradient
• E)increased ATP,because this would make more oxygen available in the mitochondrial matrix
