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.
The global rates of photosynthesis and cellular respiration influence the amount of carbon dioxide in the atmosphere. In the summer, the high rate of photosynthesis uses up much of the carbon dioxide in the atmosphere, and the amount of atmospheric carbon dioxide decreases.
