WebHigher concentrations cause more collisions between the molecules. With more molecules and more collisions, enzymes are more likely to encounter molecules of reactant. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. WebFeb 8, 2024 · Salt concentration is known to affect enzyme reaction rates. In solution, sodium chloride (NaCl) dissociates into ions that can destablize the ionic bonds that hold enzymes in their proper conformations. By binding onto the enzyme and changing the shape of the active site, the ions reduce the ability of the enzyme to process the substrate.
