Substrate availability and enzyme activity

Web29 Oct 2024 · The process of enzymatic activation starts with the binding of a substrate, or reacting molecule, to the active site of an enzyme. The active site refers to a portion of the enzyme that has the ... WebThe substrate is the reactant within the reaction that fits with the enzyme. Once the substrate enters the enzyme’s active site, the enzyme’s shape changes to form an enzyme-substrate complex. The substrate is then metabolized or broken down, resulting in a product, which can be utilized to energize cells.
