- Discuss the role of enzymes in metabolic regulation by describing the following mechanisms.11.1Cellular compartmentalization 11.2 Covalent modification11.3 ZymogensHow do non-competitive inhibitors affect KM and Vmax? (explain with details) Feedback inhibition typically impedes the activity of the enzyme that catalyzes the first committed step of a metabolic pathway, rather than an enzyme that catalyzes a later step in the pathway. Why is this adaptive?Using glucose metabolism, justify the following statement: Metabolic pathways are highly interdependent and are exquisitely controlled by enzyme activity levels and substrate bioavailability.
