Cellular respiration and photosynthesis

When mammals get an infection, their internal body temperature often rises 2 or 3 degrees Celsius. The body gets the energy it needs to react to an infection by--

• increasing the rate of cellular division

• decreasing the rate of glucose movement into the cell

• increasing the rate of cellular respiration in mitochondria

• decreasing the rate at which carbon dioxide is removed from the cell
