Warmer environments significantly limit the efficiency of photosynthetic carbon assimilation because the progressive increase in temperature tilts the balance away from photosynthesis (carboxylation) and toward photorespiration (oxygenation)

Warmer environments have the effect of: Increasing the oxygenase activity of rubisco more than the carboxylase activity.

#Unit 6. System Physiology – Plant

Warmer environments have the effect of: Reducing the stomatal aperture to conserve water. The stomatal closure lowers the uptake of atmospheric CO2, thereby decreasing CO2 at the active site of rubisco.
