How is metabolism regulated
(Integrates with Chapter 15.) Metabolic regulation is achieved via regulating enzyme activity in three prominent ways: allosteric regulation, covalent modification, and enzyme synthesis and degradation. Which of these three modes of regulation is likely to be the quickest; which the slowest For each of these general enzyme regulatory mechanisms, cite conditions in which cells might employ that mode in preference over either of the other two.
