Why do increased temperatures cause the rates of photosynthesis to slow down?

Hi! the increased temperature cause the rates of photosynthesis to slow down beacuse the enzymes involved in the chemical reactions of photosynthesis are temperature sensitive and destroyed at higher temperature.

However, for photosynthesis at temperatures above 40°c the rate slows down. This is because the enzymes involved in the chemical reactions of photosynthesis are temperature sensitive and destroyed at higher temperature. This is because heat energy causes more Collision between the enzyme and the substrate.
