Enzyme Inhibition: Competitive, Non-Competitive, and Allosteric Regulation
Students will investigate passive transport mechanisms, including diffusion and osmosis, and their importance in maintaining cellular homeostasis.
About This Topic
Students will investigate passive transport mechanisms, including diffusion and osmosis, and their importance in maintaining cellular homeostasis.
Key Questions
- Distinguish between competitive, non-competitive, and irreversible inhibition at the molecular level, predicting the effect of each inhibition type on the Michaelis-Menten curve and explaining the change in Km and Vmax values observed.
- Analyse how allosteric inhibition and feedback inhibition enable cells to regulate the flux through metabolic pathways in response to changing concentrations of substrates, products, and signalling molecules.
- Evaluate the therapeutic rationale for designing competitive inhibitors as drugs, using statins as an example, including the implications of dose-response relationships, reversibility, and the potential for drug resistance through target mutation.
