Exuberant metabolism

Metabolism is a general term for all chemical reactions in living cells. It includes two aspects of substance metabolism and energy metabolism. The metabolism of various organisms is different in the stages of growth, development and aging. Young babies and adolescents are in the process of growing their bodies and need more material to build their own bodies. Therefore, their metabolism is strong and assimilation is dominant. In old age and old age, human body functions are gradually degraded, metabolism gradually slows down, and the primary and secondary relations of assimilation and alienation are transformed.
