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 R form
The plot of V vs. [S] would be shaped like a hyperbola
