Yet, your body’s proteins are in a constant state of turnover. Want to see the full answer? I agree with what Dr Hasan said, because the synthesis of enzymes in the form of zymogens is one of the "safety mechanisms" that the body has for its survival. 180, Issue 4090, pp. Regulating body temperature The human body is designed to function most efficiently at 37ºC. 1. any of a group of compounds that are inactive precursors of enzymes and require some change (such as the hydrolysis of a fragment that masks an active enzyme) to become active Familiarity information: ZYMOGEN used as a noun is very rare. By Beatrice Kassell, John Kay. The inactivating piece which is cleaved off can be a peptide unit, or can be independently folding domains comprising more than 100 residues. Your body needs protein for growth and maintenance of tissues.. Advice that fits in with busy lives. English  Etymology .

Learn more about the composition, form, and physical adaptations of the human body. Digestive enzymes are made as zymogens and are stored in zymogen granules.  Another partially inactivated pepsinogen completes the activation by removing the peptide, turning the pepsinogen into pepsin. 7 letter Words made out of zymogens. If you become too hot or too cold, there are ways in which your body temperature can be controlled. arrow_back. A zymogen requires a biochemical change for it to become an active enzyme.

Check out a sample textbook solution. By splitting the protein into specific fragments, the zymogen is turned into an active enzyme that can itself split particular peptide…, Proteolytic enzymes are secreted as zymogens, which are themselves converted by proteolysis to their active forms.
