In the Lineweaver-Burk double reciprocal plot the horizontal intercept is equal to __________. A) 1/[S] B) 1/V C) K_m/V_max D) 1/V_max E) -1/K_m

Question

Quizplus · Accepted Answer

The horizontal intercept of a Lineweaver-Burk plot, which is a double reciprocal plot of enzyme kinetics, is equal to -1/Km. This is because the plot is a transformation of the Michaelis-Menten equation into a linear form, where the x-intercept represents the negative reciprocal of the Michaelis constant (Km). Choice E, despite its complex notation, is the only one indicating a negative reciprocal, aligning with the concept of -1/Km.
