Alex787 [66]

Answer: Options are not given, here are the options.

a.Thylakoid membranes become more permeable to ions

b.The chlorophyll breaks down

c.The peripheral proteins lose their ability to bind to the transmembrane proteins

d.Water cannot bind to PSII to form oxygen

The correct option is C.

The peripheral proteins lose their ability to bind to the transmembrane proteins.

Explanation:

In photosystem 11, it is the center where light is converted to moving electrons. When the chlorophyll molecule absorb light, the electrons gain energy.

Increase temperature affects the activity of photosystem 11 because the peripheral protein lose their ability to bind to the transmembrane protein which is as a result of high temperature affecting the surface of ionic interactions which is for binding to transmembrane protein.
