Solution: Part B
Assumptions: ✓ Michaelis-Menten kinetics ✓ Resistance due to the liquid film is negligible ✓ Bulk concentration = Interfacial substrate concentration
Solution: Part B
In Michaelis-Menten Kinetics: ✓ Vm – reaction rate at which all enzyme molecules are saturated with the substrate ✓
Ks – the concentration of the substrate at which the rate of the enzyme is half the maximum rate
