- destructive metabolism; the breaking down in living organisms of more complex substances into simpler ones, with the release of energy (opposed to anabolism).
Origin of catabolism
Examples from the Web for catabolism
In this way, anabolism and catabolism exist in balance with each other and are the ying and the yang of metabolism.
In catabolism, cells break down those large molecules to release energy and dispose of waste.
We have seen that a centre of catabolism is a hypertonic focus of diffusion.
Every centre of catabolism is therefore a positive pole of diffusion.
Swelling of the spleen is caused by catabolism of the Malpighian bodies.Valere Aude
He thinks of the world as an animal organism subject to what are now called anabolism and catabolism.The Legacy of Greece
Similar considerations as to the formation and breaking up of the molecules in anabolism and catabolism apply to polymerization.
- a metabolic process in which complex molecules are broken down into simple ones with the release of energy; destructive metabolismCompare anabolism
Word Origin and History for catabolism
1876, katabolism, "destructive metabolism," from Greek katabole "a throwing down" (also "a foundation"), from kataballein "to throw down," from kata- "down" (see cata-) + ballein "to throw" (see ballistics). Barnhart says probably formed in English on the model of metabolism. Spelling Latinized from 1889.
- The metabolic breakdown of complex molecules into simpler ones, often resulting in a release of energy.
- The phase of metabolism in which energy, in the form of ATP, is produced by the breakdown of complex molecules, such as starches, proteins and fats, into simpler ones. Compare anabolism.
