Acatalyst is a substance that enables a chemical reaction to proceed at a faster rate. how do enzymes enable a chemical reaction to proceed at a faster rate?

Enzymes latch on and lock together and enzymes have a higher activation energy in comparison to catalysts eg: amylase in saliva helps break down the large molecules in food and releases glucoses from starch

Metabolism is a collection of chemical reactions that take place in the body's cells. Metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions.
