The K_m of an enzyme is the same at all concentrations of that enzyme. (True or False) The V_max of an enzyme is the same at all concentrations of that enzyme. (True or False) The k_cat of an enzyme is the same at all concentrations of that enzyme. (True or False)

Solution

2. The K_M of an enzyme is the same at all concentrations of that enzyme. True. K_M is the substrate concentration where the rate is Vmax/2. K_M does not vary with change in enzyme concentration. 3. The V_max of an enzyme is the same at all concentration of that enzyme. False. V_{max is directly proportional enzyme concentration. 4.} The K_cat of an enzyme is the same at all concentrations of that enzyme. False. K_cat depends on enzyme concentration.
