Practice: A Lineweaver-Burk plot is used to:

Concept #3: X & Y-Intercepts of a Lineweaver-Burk Plot

Practice: To determine the Vmax from a Lineweaver-Burk plot you would:

Practice: A Lineweaver-Burk plot generates a line with the following formula: y = 0.3x + 0.4. What is the Km?

Practice: Consider the equation for the line on the following Lineweaver-Burk plot: y = 6x + 3

A) What is the Km for the corresponding enzyme?

a) -2 mM 

b) 18 mM 

c) 2 mM 

d) 9 mM

B) What is the Vmax for the corresponding enzyme?

Practice: Suppose the data on the right is plotted onto a Lineweaver-Burk plot to obtain a straight line.

A) What is the value of the y-intercept of the line? ____________

B) What is the value of the x-intercept of the line? ____________
