Enzymes can be inactivated by certain chemical substances in the body called inhibitors. Enzymes are biological catalysts that help to speed up chemical reactions in the body. They do this by lowering the activation energy required for the reaction to occur. However, enzymes can be inhibited by certain chemical substances that can bind to them and prevent them from functioning properly. These substances are called inhibitors. Inhibitors can be either competitive or non-competitive. Competitive inhibitors bind to the active site of the enzyme and prevent the substrate from binding. Non-competitive inhibitors bind to other parts of the enzyme and change its shape, making it unable to bind to the substrate. Inhibitors can have important therapeutic applications. For example, drugs that inhibit certain enzymes can be used to treat diseases such as cancer and viral infections. Therefore, enzymes can be inactivated by certain chemical substances in the body called inhibitors.
