A substance, often an enzyme, that speeds up or changes the rate of a chemical reaction in living organisms.
Enzymes act as biocatalysts to help break down food in our bodies.
Biocatalyst → It is formed from "bio-" (from Greek "bios", meaning life) and "catalyst" (from Greek "katalusis", meaning dissolution or breaking down). A biocatalyst is a substance that facilitates a chemical reaction in living organisms, thus relating to life and the process of breaking down substances.
Think of 'bio-' meaning life and 'catalyst' as something that helps break down substances. This helps you remember that a biocatalyst is something that aids in chemical reactions in living systems.
