In catabolism, cells break down those large molecules to release energy and dispose of waste.
In this way, anabolism and catabolism exist in balance with each other and are the ying and the yang of metabolism.
We have seen that a centre of catabolism is a hypertonic focus of diffusion.
Consider, on the other hand, a centre of catabolism, where the molecules are being broken up into fragments or smaller groups.
Similar considerations as to the formation and breaking up of the molecules in anabolism and catabolism apply to polymerization.
The processes concerned in metabolism are chiefly those of building up, “anabolism,” and breaking down, “catabolism.”
Swelling of the spleen is caused by catabolism of the Malpighian bodies.
In catabolism, the worn particles from the cells, and the dead cells no longer useful are broken up and thrown out of the body.
Every centre of catabolism is therefore a positive pole of diffusion.
He thinks of the world as an animal organism subject to what are now called anabolism and 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.
catabolism ca·tab·o·lism (kə-tāb'ə-lĭz'əm)
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.
