Regulation Regulation of enzyme activity is achieved in a variety of ways,ranging from controls over the amount of enzyme protein produced by the cell to more rapid,reversible interactions of the enzyme with metabolic inhibitors and activators. Next chapter is devoted to discussions of enzyme regulation.Because most enzymes are proteins, we can anticipate that the functional attributes of enzymes are due to the remarkable versatility found in protein structures.
