What is Metabolism?

Metabolism refers to the chemical processes that occur within a living organism to maintain life. These processes are essential for the energy production, growth, and repair of cells.

Key Points About Metabolism:

Metabolism involves catabolism (breaking down molecules) and anabolism (building molecules).
Metabolism is regulated by hormones and enzymes.
Metabolism is influenced by factors such as age, gender, genetics, and physical activity.

Metabolic Reactions:

Metabolic reactions can be categorized into two main types:

Catabolic Reactions: These involve the breakdown of larger molecules into smaller ones, releasing energy in the process. Examples include the breakdown of carbohydrates, fats, and proteins to release energy.
Anabolic Reactions: These reactions build larger molecules from smaller ones, requiring energy. Examples include the synthesis of proteins, carbohydrates, and lipids.

Factors Affecting Metabolism:

Metabolism can be influenced by several factors, including:

Age: Metabolism tends to slow down with age.
Gender: Men generally have a higher metabolic rate than women.
Genetics: Some people may have a naturally faster or slower metabolism based on their genetic makeup.
Physical Activity: Regular exercise can increase metabolic rate.
Hormones: Thyroid hormones play a key role in regulating metabolism.
