the chemical processes through which food is changed into energy for the body to use
Metabolism refers to the complex set of biochemical processes that occur within cells to convert nutrients into energy and essential molecules for growth, repair, and maintenance. It encompasses both the breakdown of substances (catabolism) to release energy and the synthesis of molecules (anabolism) to build and maintain cellular structures. Metabolism influences the body's energy expenditure, regulation of body weight, hormone production, and overall physiological functioning. It is regulated by various factors, including genetics, age, diet, physical activity, and hormonal balance. Metabolism is a vital process that supports the body's basic functions and is closely linked to overall health and well-being.
- Metabolism involves various biochemical reactions that convert nutrients from food into energy.
- Regular exercise can boost metabolism, helping to burn calories more efficiently.
- The thyroid gland plays a crucial role in regulating metabolism by producing hormones that control metabolic rate.
- Some people have a fast metabolism, allowing them to burn calories quickly even at rest.
- Metabolism slows down with age, leading to changes in energy levels and body composition.

the rapid process in which a larval form reorganizes its body's structure and functions to emerge as a mature adult
- The swallowtail butterfly's metabolism inside the chrysalis takes about two weeks before it emerges with fully formed wings.
- In warm ponds, a tadpole's metabolism accelerates, shrinking its tail and growing its hind legs.
- Researchers observed the crab larva's metabolism as it shed its planktonic shell and developed a hard juvenile carapace.
- A sudden spike in hormones triggers the insect's metabolism, transforming its worm-like grub into a beetle.
- Seasonal cues like daylight length can influence a frog's metabolism, delaying or hastening its change from tadpole to adult.
