Chapter 8.5, Problem 2CC
Summary Introduction
To determine: Involvement of ATP in the feedback inhibition of a catabolic pathway.
Introduction: Feedback inhibition is a mechanism in multistep pathways that aids in ceasing the reaction when one of the substrates is over produced. The substrate that is being over produced bind to one of the enzymes of the reaction. This will in turn stop the whole cycle of reactions because each step is interdependent.

(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 the.se three modes of regulation is likely to be the quickest; which the .slowest?
