What is the name of the group of molecules used specifically to speed up metabolic reactions?


Quick Answer

Enzymes are biological catalysts that speed up and control metabolic processes in the body. They are small proteins that are crucial in maintaining a homeostatic system in the human body.

Full Answer

Enzymes are small, organic molecules that are specific to one reaction or group of reactions. Each enzyme has its own substrate to which it binds in order to activate a reaction. Without binding to the substrate, enzymes cannot activate reactions. Enzymes and substrates bind loosely together until a reaction is complete, at which point the enzyme is released and can be reused to bind to another similar substrate. Since enzymes and substrates do not bind together with chemical bonds, the enzyme remains unchanged throughout the reaction that it activates. Metabolic processes in the body are catalyzed by enzymes at a continuous rate.
