Given an enzyme with a Km = 10m M and Vmax = 100 m mol/min. If [S] = 100 m M, which of the following will be true?

• A 10 fold increase in Vmax would increase velocity 10 fold y
• A 10 fold decrease in Km would increase velocity
• Both (a) and (b)
• A 10 fold increase in Vmax would decrease velocity 20 fold
