"metabolism"的定义和意义

What is "metabolism"?

Metabolism refers to the complex set of biochemical processes that occur within cells to convert nutrients into energy and essential molecules for growth, repair, and maintenance. It encompasses both the breakdown of substances (catabolism) to release energy and the synthesis of molecules (anabolism) to build and maintain cellular structures. Metabolism influences the body's energy expenditure, regulation of body weight, hormone production, and overall physiological functioning. It is regulated by various factors, including genetics, age, diet, physical activity, and hormonal balance. Metabolism is a vital process that supports the body's basic functions and is closely linked to overall health and well-being.
