Inactivated enzymes
WebEnzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain … WebWhen a ligand binds to a cell-surface receptor, the receptor’s intracellular domain (part inside the cell) changes in some way. Generally, it takes on a new shape, which may make it active as an enzyme or let it bind other molecules. The change in the receptor sets off a series of signaling events.

WebOnce in the liver, enzymes convert prodrugs to active metabolites or convert active drugs to inactive forms. The liver’s primary mechanism for metabolizing drugs is via a specific group of cytochrome P-450 enzymes. The level of these cytochrome P-450 enzymes controls the rate at which many drugs are metabolized. cynlynnWebRecent research suggests that lysosomes are organelles that store hydrolytic enzymes in an inactive state. The system is activated when a lysosome fuses with another particular organelle to form a ‘hybrid structure’ where the digestive reactions occur under acid (about pH 5.0) conditions. cyn lyn creationsWebEnzyme inactivation involves exposing these compounds to conditions utterly different from those you would commonly find within its environment (living cells).
