The Effect of Temperature on Trypsin Activity

... The Effect of Temperature on Trypsin Activity Introduction: Enzymes are protein molecules, which can be defined as biological catalysis. A catalyst is a molecule, which speeds up the chemical reaction, but remains unchanged at the end of the reaction. Virtually every metabolic reaction, which takes place within a living organism, is catalysed by an enzyme. Enzymes are globular proteins. Like all globular proteins, enzymes molecules are coiled into a precise three-dimensional shape, with hydrophilic side-chains on the outside of the molecules ensuring that they are soluble. Enzymes molecules also have special feature in that they possess an active site. The active site of an enzyme is a region of the molecule, usually a cleft or depression, to which another molecule or molecules can bind. This molecule is the substrate of the enzymes. The shape of the active site allows the substrate to fit perfectly, and to be held in place by temporary
