An allosteric enzyme that is analogous to atcase and follows the concerted mechanism (mwc model) has a 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 mostly be in the t form. the plot of v vs. [s]would be shaped like an s, sigmoidal. the enzyme would likely follow michaelis-menten kinetics. the enzyme would be more active. the plot of v vs. [s] would be shaped like a hyperbola.
