Root Explanation

**Lyase** → The word 'lyase' is derived from the Greek root 'lyein' (meaning to loosen or to break down) combined with the suffix '-ase' (used in biochemistry to denote enzymes). Thus, 'lyase' refers to an enzyme that catalyzes the breaking down of a compound without the addition of water, effectively loosening or breaking it down.

Memory Tip

Think of 'lyein' meaning to 'loosen' or 'break down' — that's why a lyase is an enzyme that helps break down compounds.
