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 /ËÉnzaÉªmz/ are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.nzymes differ from most other catalysts by being much more specific. Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.
