A tomato plant is mutated with gamma radiation. A cellular analysis reveals that ATP synthase complexes found in the thylakoid membrane are inserted backward into the membrane. What is the most likely outcome of this error?
A. The proton gradient in the thylakoid space will not be able to be used to generate ATP B. A proton gradient will not be established in the thylakoid space in response to the activation of photosystem II C. The ATP synthase will pump protons into the stroma in this orientation D. This change is not likely to have any effect on the function of the ATP synthase enzyme with respect to its role in photosynthesis E. The thylakoid membrane will become permeable to protons as a result of this change
