Root Explanation

Proteolysis → It is formed from "proteo-" (from Greek "proteios", meaning primary or first) and "lysis" (from Greek "lysis", meaning to break down or dissolve). The word describes the process of breaking down proteins into smaller peptides or amino acids.

Memory Tip

Think of 'proteo-' meaning primary or first, as proteins are fundamental to life, and 'lysis' meaning to break down, which helps you remember that proteolysis is the breakdown of proteins.
