Question

What do catalysts, like enzymes, do to chemical reactions?

Answer 1

❣Enzymes are proteins functioning as catalysts that speed up reactions by lowering the activation energy.

❣A simple and succinct definition of an enzyme is that it is a biological catalyst that accelerates a chemical reaction without altering its equilibrium.

Answer 2

Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.
