Metabolism is a chemical process necessary for organisms to maintain life activities. It includes two basic processes: synthesis and decomposition. In this chemical operation, organisms release energy and use this energy to maintain their growth, division, tissue repair and comfortable living standards. The process of metabolism consists of a series of basic chemical reactions, which are carried out under the action of specific enzymes. The activity of these enzymes is influenced by many factors, such as temperature, pH value, ion concentration and so on. The metabolic process forms a stable dynamic balance, which enables organisms to maintain life in a constantly changing environment.

The importance of metabolism to human health is self-evident. The intensity of metabolic activity is closely related to health. Poor metabolism can lead to obesity and metabolic syndrome, including cardiovascular disease, diabetes, fatty liver and hypertension. In addition, poor metabolism may also lead to energy loss, which in turn leads to the loss of body organs and the death of tissues. Therefore, in daily life, maintaining a reasonable diet, exercise and routine is an important measure to maintain metabolism and health.

The study of metabolism is of great significance to human health and various bioengineering activities. With the development of gene editing and other technologies, the prospect of metabolic engineering is constantly expanding and improving. People can produce efficient Saccharomyces cerevisiae, fuels and drugs by changing the expression pattern of biological genes, regulating metabolic processes and developing new enzymes. In the future, metabolic engineering will be one of the important cross fields of neuroscience, nanotechnology and other important disciplines, which will greatly promote the development direction of biotechnology.
