What is human metabolism?
Human metabolism is the set of chemical reactions that convert food and nutrients into energy and materials needed for growth, repair, and normal body function.
What are the two main types of metabolism?
The two main types are catabolism, which breaks down molecules to release energy, and anabolism, which uses energy to build molecules and tissues.
What is basal metabolic rate (BMR)?
Basal metabolic rate is the energy the body uses at rest to maintain essential functions such as breathing, circulation, and temperature regulation.
How does metabolism produce energy?
Metabolism converts carbohydrates, fats, and proteins into ATP, the main energy-carrying molecule used by cells.
What role does insulin play in metabolism?
Insulin helps cells take up glucose from the blood and promotes storage of glucose, fat, and other nutrients after meals.
How are carbohydrates, fats, and proteins metabolized?
Carbohydrates are primarily converted to glucose, fats to fatty acids, and proteins to amino acids, which can be used for energy or body tissues.
What factors affect human metabolism?
Metabolism is affected by age, body size, muscle mass, genetics, hormones, activity level, diet, sleep, and health conditions.
