Difference Between Substrate And Active Site |top| -

The Central Role of Enzymes as Biological Catalysts - The Cell - NCBI

The primary difference between a and an active site is that the substrate is a chemical reactant that undergoes a change, whereas the active site is the specific physical location on an enzyme where that change occurs. Key Differences at a Glance Active Site Nature A molecule (chemical substance). A region/pocket on a protein (enzyme). Role The reactant that is transformed into a product. The location that catalyzes the reaction. Change Is chemically altered and released as a new product. Remains chemically unchanged and is reused. Composition Can be sugars, proteins, fats, or other molecules. Composed of a specific sequence of amino acid residues. Detailed Breakdown difference between substrate and active site
