an allosteric enzyme that follws the concerted mechanism (MWC model) has T/R ratio of 300 in the absence of substrate. Suppose that a mutation reversed the ratio. How would this mutation affect the relationship between the rate of the reaction (V) and substrate concentration ([S])? Select all that apply. The enzyme would be less active The enzyme would likely follow Michaelis-Menten kinetics The plot of V vs. [S] would be shaped like an S, sigmoidal The enzyme would be mostly in the...
