Enzymes are a type of globular protein that function within the human body as catalysts for other biochemical reactions. Catalysts are agents within a specific reaction that are able to quicken the reaction process without being altered themselves. Substances that these enzyme catalysts are able to convert into products are labelled as substrates. In order for the enzyme to catalyse the specific biochemical reaction, the substrate must bind to a special region on the surface of the globular enzyme (known as the active site). However, the shape and chemical properties of the active site and the substrate must match each other in order for the reaction to proceed. Suggesting that each individual enzyme has a specific substrate that they are able
