Simple definition of enzyme
WebbThe enzyme is a tetramer of four polypeptide chains wherein every chain possesses more than 500 amino acids. It contains 4 iron-containing heme groups which are key, enabling it to react with the hydrogen peroxide. The optimal pH level for human catalase is nearly 7. WebbEnzymes are biological catalysts that help living organisms speed up chemical reactions. Enzymes can only function in specified pH, pressure, and temperature conditions. Each chemical response in the body, they are highly specific and effective. They also reduce the activation energy necessary to start the reaction, resulting in a faster response.
