WebSep 2, 2013 · 1. Introduction. Leonor Michaelis and Maud Menten are often regarded as the founders of modern quantitative enzymology. In their studies on invertase [1], they recognised the necessity of assaying the enzyme under defined and controlled conditions, principally with respect to the pH of the reaction, and the need to measure initial rates, … WebA higher temperature generally makes for higher rates of reaction, enzyme-catalyzed or otherwise. However, either increasing or decreasing the temperature outside of a tolerable range can affect chemical bonds in the active site, making them less well-suited to bind substrates.
