Lisa is running an experiment to determine the kinetic parameters (Kmand Vmax) of the enzyme that she is studying. She has run a series of experiments where she changed the amount of substrate added and measured the accumulation of product over a 5 second time interval. She used this data to calculate the dependence of the rate of the reaction on substrate concentration. Her results listed below. Substrate Concentration (mM) Velocity (mM/sec) 1 2 5 2.5 4 6.3 10 7.6 20 1. Using this information construct a Michaelis-Menten curve. 2. Using this information construct a Lineweaver-Burk plot. 3. Using the Lineweaver-Burk plot determine the values of Km and Vmax.

Question
Hello, can someone please help me? I have already hand graphed 1 and 2 and found the v max, however I cannot find the Km value. I am confused because the plots on the linear weaver burk plot do not extend past the values that make up the line. So how am I supposed to estimate the value for the y-intercept in order to find the Km value
