The metabolization process of a substance acts as a body's defense system, leading to the modification of foreign substances (xenobiotics) by chemical processes to promote their elimination from the organism (20).

The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes.

Metabolism is how your body turns food and drink into energy to keep you alive and functioning. It’s made up of all the chemical processes happening in your body’s cells every second. These processes help you breathe, move, heal and more. Keeping these processes balanced is called homeostasis. It’s what keeps your body running smoothly.

2025年1月31日 · metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.

2022年9月12日 · Metabolism refers to the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy. This energy gets used for vital processes and the synthesis of new organic material.

2023年2月8日 · "Metabolism" is a term that refers to all chemical processes or changes in your body at the cellular level. At any given moment, thousands of complex chemical processes are happening in your cells to keep you healthy and thriving.

Metabolism consists of a series of reactions that occur within cells of living organisms to sustain life. The process of metabolism involves many interconnected cellular pathways to ultimately provide cells with the energy required to carry out their function.
