When the adrenal gland is in a state, the amount of cortisol production drops below the normal level, and the amount of sugar available to the cells is reduced. With less sugar, less energy is available to the body, and fatigue is experienced.
The higher the temperature then typically the greater the rate of photosynthesis, photosynthesis is a chemical reaction and the rate of most chemical reactions increases with temperature. However, for photosynthesis at temperatures above 40Â°C the rate slows down.
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. 1  Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. 2  Carbon dioxide concentration.
