Enzymes

Enzymes Enzymes are proteins, composed of polypeptide chains and non-protein groups. Their function is to help with the replys of many another(prenominal) cells and molecules by serving as accelerators. A catalyst is a substance that allows the activation energy required for a reaction by forming a temporary association with the molecules that are reacting. During this process, the catalyst itself is not permanently altered in the process, and so it gouge be used over and over again. Because of catalysts, cells are open to carry out chemical reactions at a outstanding speed and at comparative low temperatures.

Almost 2,000 unlike enzymes are now known, each of them capable of catalyzing a ad hoc chemical reaction. The molecule (s) on which an enzyme acts is known as its substrate. For example, sucrose is the substrate for the enzyme sucrase. Enzymes have specific structures that only its specific substrate will fit into. The polypeptide chains of an enzyme are folded in much(prenominal) way that they form a ...If you want to get a full essay, order it on our website: Ordercustompaper.com
