Enzyme Kinetics Equations

Question 1

Michaelis-Menten Equation

Answer 1

(V / Vmax) = ([S] / Km + [S])

Question 2

Kcat

Answer 2

Vmax / Amount of enzyme (eg, mols)

Question 3

Equation used to compare the effciency of enzyme controlled reactions

Answer 3

Ki = Kcat / Km

Question 4

Competitive Inhibition

Answer 4

Km (I) = Km (1 + [I} / Ki)

Increases Km

Question 5

Non-Competitive Inhibition

Answer 5

Vmax / Km (I) = Vmax / Km (1 + [I} / Ki)

Decreases Vmax

Question 6

Uncompetitive Inhibition

Answer 6

1 + [I] / Ki

Vmax and Km Decrease
