Root Explanation

Phosphokinase → It is formed from "phospho-" (from Greek "phosphoros", meaning light-bearing or phosphorus) and "kinase" (from Greek "kinein", meaning to move). The word refers to an enzyme that catalyzes the transfer of a phosphate group, thus facilitating movement or energy transfer in biological systems.

Memory Tip

Think of 'phospho-' as relating to something that carries light or energy, and 'kinase' as something that moves or transfers. This helps you remember that phosphokinase is an enzyme that transfers energy in the form of phosphate.
