Question: What is animal metabolism?

An animal’s metabolic rate determines how much food it must consume to maintain its body at a constant mass. If an animal doesn’t eat enough food to replace the energy it uses up, it will lose body mass (as glycogen, fats, and other macromolecules are burned for fuel).

What affects animal metabolism?

The two factors underlying most of this variation are well known: body mass and higher-level taxonomic affiliation. … (Metabolic rate per g of body mass decreases with body mass but by a power smaller than 1.0, so the absolute metabolic rate of a whole animal, the subject of this paper, increases with mass).

What is metabolism easy definition?

Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
