Question: The Effect of pH on the Rate of Catalase
Answer: Catalase is an enzyme. All enzymes are proteins, made up of a string of chemically bonded amino acids which each contain variable -R groups that give them different properties.
The theory that explains catalysation is known as the ‘lock & key’ theory. This states that the enzyme has an area on it, which is a specific shape that compliments the structure of the substrate; this is known as the active site. The substrate bonds with the active site and forms an enzyme-substrate complex, the bonds are strained and the ES complex splits releasing the new products....(short extract)
