What processes does the body spend energy on?

Energy is always consumed by the body, even during sleep. It is received by the body during meals, during the breakdown of chemicals. There is a basic metabolism and an additional expenditure of energy. Basal metabolism is needed for minimal maintenance of life. These are processes such as respiration, the work of organs, maintaining constant cell division, maintaining muscles in a minimum tone. Additional processes include the expenditure of energy for digestion, mental activity, emotional experiences.
