Additional Information

Metabolism is a complex process that involves the breakdown of nutrients from food into energy, which is then used to power the body’s various functions. A person’s metabolic rate can be influenced by factors such as genetics, diet, and exercise. Understanding metabolism is important for maintaining a healthy weight and overall well-being.

There are three main stages of metabolism: catabolism, anabolism, and cellular respiration. Catabolism is the process of breaking down nutrients into energy, anabolism is the process of building new tissues and repairing existing ones, and cellular respiration is the process of generating energy from the breakdown of nutrients.

Metabolism can be affected by various factors, including age, sex, and body composition. For example, metabolism tends to slow down with age, and women generally have a slower metabolism than men. Additionally, people with a higher percentage of muscle mass tend to have a faster metabolism than those with a higher percentage of body fat.

The word “metabolism” comes from the Greek words “meta,” meaning “beyond” or “transcending,” and “bolismos,” meaning “throwing” or “casting.” The term was first used in the 19th century to describe the process of chemical change that occurs within living organisms.
