Definition of catabolism in English:
catabolism
noun kəˈtabəlɪz(ə)mkəˈtæbəˌlɪzəm
mass nounBiology The breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism.
Example sentencesExamples
- Ammonium produced by catabolism of protein is then excreted in urine.
- Muscle catabolism is a hallmark of sepsis and results from accelerated breakdown of myofibrillar proteins, such as actin and myosin.
- The various reactions which involve the synthesis of complex molecules can be grouped under the heading of anabolism, whereas the breakdown of complex molecules is known as catabolism.
- During normal catabolism, protease enzymes break down carboxylase enzymes and reclaim the associated amino acids and biocytin for recycling.
- The process, in which the body basically metabolizes itself, is called catabolism and leads to muscle loss and weakness.

Biology There are thus a number of different requirements for mitochondrial metabolism, ranging from biosynthesis to catabolic processes that may or may not result in ATP synthesis.
Example sentencesExamples
- Alanine and glutamine account for about 80% of the amino acids released from skeletal muscle during catabolic periods such as intense training or injury.
- You can help prevent your body from becoming catabolic by supplying it with all the necessary nutrients at the time when it needs them the most - during intense workouts.
- There they are converted to fatty acids, amino acids, and glycogen, or else oxidized by the various catabolic pathways of cells.
- During catabolic stress intracellular glutamine levels can drop more than 50 percent, and it is under these circumstances that supplemental glutamine becomes necessary.
verbkəˈtabəlʌɪzkəˈtæbəˌlaɪz
[with object]Biology (of a living organism) process (a substance) by the breakdown of complex molecules to form simpler ones, together with the release of energy.
when starvation is present, the body will catabolize its own muscle protein
Example sentencesExamples
- However, birds may preferentially catabolize assimilation organs to avoid catabolizing flight muscles that could impair flying ability.
- As a result, a bird with large glycogen stores may catabolize less protein to maintain blood glucose levels during migration than a bird with small glycogen reserves.
- Over time, your body begins to catabolize muscle tissue, converting it to glucose for energy.
Origin
Late 19th century: from Greek katabolē 'throwing down', from kata- 'down' + ballein 'to throw'.
