Question

2. Why does the photosynthesis stops above 40℃ temperature?who will answer first brainlest​

Answer 1

Answer: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 temperatures.

Answer 2

Answer:

At high temperatures (20–40 C), the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves. ... Above the optimum temperature the rate begins to decrease, as enzymes are denatured, until it stops.
