Which of the following is not the effect of C3 and C4 cycle in hot and dry climates ?

#Unit 6. System Physiology – Plant

elevated temperatures limit the rate of photosynthetic CO2 assimilation in C3 plants by decreasing the solubility of CO2
In C4 plants warm climates decrease the levels of CO2, but the low concentrations of cytosolic HCO3 − saturate PEP Case because the affinity of the enzyme for its substrate is sufficiently high
The optimal photosynthetic efficiency of C3 species generally occurs at temperatures lower than for C4 species
C4 species become less abundant in the tropics and subtropics and more abundant when latitudes depart from the equator
