WebApr 10, 2024 · Therefore, the enzyme must interact with the membrane to entice the substrate into its active site. Membrane binding induces a conformational change that makes a productive enzyme-substrate complex and therefore enables extraction of the substrate from the membrane. WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product. grams of protein in 1 oz cheese
