What term describes the overall sum of chemical processes occurring within the body that convert food into usable energy and support essential life functions?

Explanation

Metabolism refers to the overall sum of chemical processes occurring continuously within the body that convert food into usable energy, while also supporting the ongoing building and breakdown of various molecules needed to sustain essential life functions and support growth and repair. This includes both processes that build up more complex molecules from simpler ones, requiring energy input, as well as processes that break down complex molecules to release stored energy for the body to use. Metabolic rate, meaning how quickly a person’s body uses energy, can vary based on factors such as age, muscle mass, and overall activity level.
