BCH 369 CHAPTER 7 TEST QUESTIONS WITH ANSWERS ALL REVISED AND UPDATED Michaelis-Menten equation - Answer-A mathematical expression that describes the activity of an enzyme in terms of the substrate concentration ([S]), the enzyme's maximal velocity (Vmax), and its michaelis constant (Km): Vo = Vmax [S]/(Km + [S]). catalytic constant (Kcat) - Answer-The ratio of the maximal velocity (Vmax) of an enzyme-catalyzed reaction to the enzyme concentration. Also called a turnover number. Turnover...
