What is an enzyne.

Enzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.What are Enzymes. Enzymes are special proteins that are found in the cells of living organisms. Like any other protein, enzymes are also made up of long chains of amino acids held together by peptide bonds. Enzymes play an important role in performing or controlling a host of chemical reactions that take place in the body.Jul 13, 2023 · Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonuclease P, by Sid Altman’s laboratory. Lipoprotein lipase (LPL) is an extracellular enzyme on the vascular endothelial surface that degrades circulating triglycerides in the bloodstream.
