Which of the following statements about the challenges of C3 photosynthesis under hot conditions is TRUE? When they close stomatal cells, they save water but lose too much O2. O Rubisco has a higher affinity for CO2, making the rate of photosynthesis too rapid. O When stomatal cells close, photorespiration increases and CO2 is lost. O C3 plants have to spend energy to store carbon in a separate specialized cell.

Introduction
C3 Cycle: It is a cyclic reaction that occurs during the dark phase of photosynthesis. This cycle involves conversions of CO2 into sugar and hence it is a process of carbon fixation. It is also known as Calvin Cycle
Net Reaction of the cycle :
3CO2 + 5H2O + 6NADPH + 9ATP-----------glyceraldehyde - 3 - phosphate+ 6NADP+ + 3H+ + 9 ADP + 8Pi
Usually majority of plants and trees perform C3 cycle like wheat,cotton,grasses and, etc.
