Question 1

What are the factors that affect reaction rate of enzyme catalyzed reactions?

Answer 1

• Temperature
• Reactant Concentration
• Hydrogen Ion Concentration
• Sunstrate Concentration

Question 2

K_m

Answer 2

The substrate concentration at which v_i is half the maximal velocity (v_max/2) attainable at a particular concentration of the enzyme.

Question 3

V_max

Answer 3

Maximal Velocity

Question 4

k_cat

Answer 4

Catalytic Constant

Question 5

k_cat/K_m

Answer 5

The specificity constant, it tells you “catalytic efficiency” which means how fast in m/s the enzyme reacts with the substrate once it encounters the substrate.

Question 6

Michaelis-Menten Equation

Answer 6

v_i= (V_max [S]) / (K_m + [S])
