WebEach enzyme has a different, specifically shaped active site. This is because each type of enzyme is suited to one, or a few, particular molecules that will bind to it, called the substrates. When the substrate has bound to the enzyme’s active site, it is called an enzyme–substrate complex, as can be seen in Figure 2 below. WebNormally, a given enzyme will Catalyse only one reaction, or type of reaction. The enzyme has an active site that helps it to recognise its substrate in a very specific way.
