High temperatures and extreme pHs, the protein structure of an enzymeĬhanges, which means the active site also changes shape irreversibly. So that only one particular molecule can fit into it. They work by havingĪn active site that is complementary to the shape of a substrate molecule


They are also used commercially, for example, in synthesizing antibiotics.Įnzymes are made up of protein molecules and have a region on their surfaceĬalled the active site. That are essential to our survival such as respiration and digestion, but Only do enzymes catalyze most of the reactions occurring within our bodies Reactions can occur over a set time, increasing the rate of reaction. The activation energy required for a reaction to occur. They are biological catalysts that work by lowering They allow our cells toĬarry out the many different chemical reactions they are responsible for, PH, and substrate concentration on enzyme activity.ĭid you know that the typical human cell makes over 1 000 different enzymes? Enzymes are vitally important for all life on Earth. In this explainer, we will learn how to describe the effect of temperature,
