In your synthetic biology lab, you generated a cell that expresses a light-sensitive ATP synthase that functions normally in the dark. When the light-sensitive ATP synthase is exposed to a specific wavelength of light, the pump shuts off. How would the proton gradient in the intermembrane space of mitochondria most likely be affected if the ATP synthase was exposed to light and shut off? The intermembrane space will become highly acidic where protons are still pumping in, but cannot escape without a functioning ATP synthase O Protons will continue to move freely across the outer and inner mitochondrial membrane and the acidity of the intermembrane space will not change O The intermembrane space will reach a slightly more acidic balance where protons are still pumping in, but can only escape through the outer mitochondrial membrane
