Question

a tomato plant is mutated with gamma radiation. a cellular analysis reveals that atp - synthase complexes found in the thylakoid membranes are inserted backward into the membrane. what is the most likely outcome of this error? multiple choice the proton gradient in the thylakoid space will not be able to be used to generate atp the atp synthase will pump protons into the stroma in its orientation a proton gradient will not be established in the thylakoid space in response to the activation of photosystem ii the thylakoid membrane will become permeable to protons as a result of this change this change is not likely to have any effect on the function of the atp - synthase enzyme with respect to its role in photosynthesis

Explanation:

ATP synthase in thylakoid membranes uses the proton - gradient across the membrane to synthesize ATP. If ATP synthase complexes are inserted backward, the proton gradient in the thylakoid space cannot be harnessed to generate ATP as the enzyme's orientation is crucial for its function. Protons flow through ATP synthase in a specific direction to drive ATP synthesis. The normal orientation allows protons to flow from the thylakoid space to the stroma while generating ATP. When inserted backward, this process is disrupted.

Answer:

The proton gradient in the thylakoid space will not be able to be used to generate ATP
