An allosteric enzyme that 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. Note that R is the highly active form of the enzyme and T is the less active form of the enzyme. Select all of the effects this mutation will have on the relationship between the rate of the reaction (V) and substrate concentration ([S])? a. The enzyme would likely follow Michaelis Menten kinetics
b. The plot of V vs. (S) would be shaped like an S, sigmoidal.
c. The enzyme would be more active.
d. The plot of V vs. (S) would be shaped like a hyperbola.
e. The enzyme would mostly be in the T form.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
