Enzyme Kinetics: Michaelis-Menten Model, Km, and Vmax
Students will analyze the fluid mosaic model of the cell membrane, understanding its composition and how it regulates the cell's interactions with its environment.
Key Questions
- Apply the Michaelis-Menten model to interpret Km and Vmax values from substrate-concentration curves, explaining what each parameter reveals about an enzyme's substrate affinity and maximum catalytic capacity.
- Analyse a Lineweaver-Burk double-reciprocal plot to determine Km and Vmax graphically, and predict how these parameters shift on the plot under conditions of competitive versus non-competitive inhibition.
- Evaluate whether a low Km value is universally advantageous for an enzyme, considering cellular contexts where substrate availability is variable and where metabolic flux control requires a graded response to substrate concentration.
