Root Explanation

Isoenzyme → It is formed from "iso-" (from Greek "isos", meaning equal or same) and "enzyme" (from Greek "enzymon", meaning leaven or ferment). The term refers to enzymes that have the same function but differ in structure, hence they are 'equal' in function but 'different' in form.

Memory Tip

Think of 'iso-' meaning 'same' and 'enzyme' referring to a biological catalyst. This helps you remember that isoenzymes are different forms of enzymes that perform the same function.
