Think of the substrate as the "raw material." Whether it’s a piece of starch being broken down into sugar in your saliva or DNA being replicated in your cells, the starting molecule is always the substrate. catalase
It contains "catalytic groups" (R-groups of amino acids) that actively participate in breaking or forming chemical bonds. Key Differences: Substrate vs. Active Site Active Site Nature A chemical molecule (reactant). A physical region on an enzyme. Fate Transformed into a product. Remains unchanged after the reaction. Function Provides the material for the reaction. Provides the environment for the reaction. Reusability Used once per reaction. Can be used thousands of times per second. Composition Can be sugar, protein, lipid, etc. Made of amino acid sequences. How They Work Together: The Models
