Paper chromatography is a method used to separate molecules that are not alike by
their molar mass and size (Sestini, 2000). It works by placing a small sample of a
mixture on a piece of filter paper, and letting a liquid pass through it (Sestini, 2000).

Enzymes are biological protein molecules made out of long chains of amino acids
that play a role in increasing rate of reaction within living cells (Castro, 2014).
Enzymes also act as catalysts to decrease the amount of activation energy required
