Step-by-step explanation:
Proteins are essential for the main physiological processes of life and perform functions in every system of the human body.
A protein’s shape determines its function.
Proteins are composed of amino acid subunits that form polypeptide chains.
Enzymes catalyze biochemical reactions by speeding up chemical reactions, and can either break down their substrate or build larger molecules from their substrate.
The shape of an enzyme’s active site matches the shape of the substrate.
