The Role of Enzymes in Living Organisms. Enzymes are macromolecules that catalyze chemical reactions within a living organism. Most are proteins, but there are also RNA enzymes which aid in protein synthesis.
Enzymes are large biomolecules that are responsible for many chemical reactions that are necessary to sustain life. Enzyme is a protein molecule and are biological catalysts. Enzymes increase the rate of the reaction. Enzymes are specific, they function with only one reactant to produce specific products. Enzymes have a three-dimensional structure and they utilize organic molecules like biotin and inorganic molecules like metal ions (magnesium ions) for assistance in catalysis.
