WebEnzymes act as catalysts to speed up the rate of chemical reactions in living cells. In most cases, they convert one chemical, the substrate, into another, the product. The Michaelis-Menten equation is commonly used to describe such reactions: Umc v=k +c (5) where v = the initial reaction velocity, Um = the maximum initial reaction velocity, c ... WebNov 20, 2016 · Enzymes are proteins which catalyze, or 'speed up', chemical reactions. 'Speeding up', also known as catalysis, is the process by which the rate of a chemical reaction increases.
