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?

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.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
