Question

what would be most likely to happen if some of the proteins in one of the photosystems were to change shape due to a rise in temperature?

Answer 1

Answer:

The correct answer will be option C.

Explanation:

Proteins are involved in light reaction of the photosynthesis are present in the five complexes: thylakoid membrane, photosystems, cytochrome bf complex, thylakoid lumen and ATP synthase. Photosystem I and II in plants are associated with the generation of ATP and NADPH molecules respectively.

If a protein changes their shape in response to temperature it will directly affect the electron transfer chain (will not be transferred) due to which H+ ions transport will also be affected which are involved in the production of ATP molecules.

Thus, option C- a decrease in ATP production is the correct answer.

Answer 2

C. A decrease in the formation of ATP
