- Enzymes
- Enzymes are protein molecules known as biologial catalysts.
- They increase the rates of reactions so that chemical reactions in living organisms can take place at normal temperatures. Enzymes lower the activation energy of a reaction so that less energy is needed to turn substrate molecules into the product.
- The molecules that enzymes act upon are called substrate molecules. The molecule produced as a result of the enzyme action on the substrate is called the product.
- The substrate fits to a part of the enzyme called the active site. The specific tertiary structure of the active site means that only substrate molecules with a complementary shape can fit into it.
- Lock and key mechanism
- Only substrate molecules with a complementary shape can fit into the active site. If a molecule does not have a shape complementary to the active site then it cannot bind to form an enzyme substrate complex.
