The correct answer is: constant .Explanation:When an enzyme is partially denatured, its active site undergoes structural changes, which can affect the binding affinity between the enzyme and the substrate. The binding affinity is characterized by the equilibrium constant , which represents the ratio of the concentration of the enzyme-substrate complex to the concentration of the free enzyme and substrate at equilibrium.Partial denaturation of the enzyme can alter the shape and properties of the active site, leading to changes in the binding affinity between the enzyme and the substrate. As a result, the equilibrium constant is most likely to be affected by the partial denaturation of the native form of the enzyme.The other options, such as the mass of the substrate, similarity to the substrate, and the products as the substrate, are not directly related to the binding affinity between the enzyme and the substrate, and therefore, they are less likely to be affected by the partial denaturation of the enzyme.
