Describe hоw enzymes lоwer аctivаtiоn energy аnd explain how allosteric regulation controls metabolic pathways. In your answer, include: The concept of induced fit and how enzymes lower activation energy. The difference between competitive and noncompetitive inhibition. How feedback inhibition works, using a real metabolic pathway example (for example, ATP inhibiting phosphofructokinase-1 in glycolysis, or another clear pathway you know).
