According to the Michaelis-Menten equation, when an enzyme is combined with a substrate of concentration s (in millimolars), the reaction rate (in micromolars /min ) is R(s)=K+sAs,(A,Kconstants) (a) Find the limiting reaction rate as the concentration s approaches by computing limsR(s). (Use symbolic notation and fractions where needed.) limiting reaction rate: (b) Find the reaction rate R(K). (Use symbolic notation and fractions where needed.) R(K)= (c) For a certain reaction, K=1.400mM and A=0.200. For which concentration s is R(s) equal to 75% of its limiting value? (Use decimal notation. Give your answer to three decimal places.)
