How does an enzyme catalyze reactions in the body?

Answer:
Enzymes are specialized proteins that facilitate chemical reactions in the body by lowering their activation energy, or the energy required to initiate a reaction. They are never consumed by the reaction themselves; therefore, enzymes can be re-used many times. Enzymes are specific to a particular substrate and usually facilitate the reaction by undergoing a conformational change when encountering the substrate, transforming it into a product or an intermediate.
