- Regarding the reasoning for the Michaelis-Menten equation to be unsuitable for accurate analysis of experimental data, select all that apply: It is nonlinear It is only valid for reactions at equilibrium It is not valid under experimental conditions Extrapolation to Vm is inaccurate and therefore Km also cannot be accurately describedarrow_forwardCalculate the equilibrium constant for the reaction glucose-1-phosphate + H2O → glucose + H2PO4− at pH 7.0 and 25°C (ΔG°′ = −20.9 kJ · mol−1).arrow_forwardMatch each inhibitor with its effect on Michaelis-Menten reactions. Group of answer choices Vmax and apparent Vmax are equal and the apparent Km is greater than Km. The apparent Vmax is less than Vmax and the apparent Km and Km are equal The apparent Vmax and the apparent Km are both lowered to the same degree. The apparent Vmax is less than Vmax and the apparent Km can be either greater than or less than Km.arrow_forward
