identify the features of a regulated metabolic pathway, list the regulated enzymes in glycolysis.
Homework Answers
The regulated Metabolic pathway is a result of enzyme regulation by the change in it signal response. Feedback inhibition will control the pathway's general rate. Both covalent and non covalent alterations results in regulation.
The enzymes are phosphofructokinase, pyruvate kinase, and hexokinase and all of these involves regulatory and catalytic activities.
hope the answer helps.
