Catalytic rate constant given Michaelis Constant Solution

Follow our step by step solution on how to calculate Catalytic rate constant given Michaelis Constant?

FIRST Step Consider the formula

k cat = (K M \cdot k f) - k r

Next Step Substitute values of Variables

∴

k cat = (3mol/L \cdot 6.9s⁻¹) - 20mol/L*s

Next Step Convert Units

∴

k cat = (3000mol/m³ \cdot 6.9s⁻¹) - 20000mol/m³*s

Next Step Prepare to Evaluate

∴

k cat = (3000 \cdot 6.9) - 20000

LAST Step Evaluate

∴

k cat = 700s⁻¹
