Most of the rest is used in basal metabolism, the energy we need when in a resting state, for functions such as blood circulation, digestion, and breathing. In a cold environment, we need more energy to maintain a constant body temperature, as our metabolism increases to produce more heat.
In a warm environment, we need less energy. Cellular respiration is the metabolic process by which cells get energy by reacting oxygen with glucose to produce carbon dioxide, water, and energy. How efficiently energy from respiration converts into physical—or mechanical— power depends on the type of food eaten, the type of physical energy, and whether muscles are used aerobically or anaerobically.
