Root Explanation

Hydrogenase → It is formed from "hydro-" (from Greek "hydor", meaning water) and "-gen" (from Greek "genes", meaning creator or producer) and "-ase" (a suffix used in biochemistry to denote enzymes). The word "hydrogenase" refers to an enzyme that produces or generates hydrogen, often in the context of biochemical reactions involving water.

Memory Tip

Think of 'water' ('hydro-') being 'produced' ('-gen') by an enzyme ('-ase'). This helps you remember that hydrogenase is an enzyme that generates hydrogen.
