Enzymes are biological catalysts that increase the rate of biological reactions occurring in the body while being themselves unchanged. All chemical reactions within cells are catalyzed by enzymes. These act as biocatalysts of the cells. They reduce the activation energy for the reaction, thereby increasing the reaction rate. But they do not affect the equilibrium. All enzymes are made up of proteins. But in addition to protein, there are also non-protein substances. Such an enzyme is known as Holozyme or Holoenzyme. Let's know more about Enzymes.
