Question 9 (2 points) Sucrose (table sugar) is hydrolyzed to glucose and fructose by the enzyme invertase. A Lineweaver-Burk plot (shown) was used to analyze the data in the table below, with and without the presence of the inhibitor urea at a 2 mM concentration. Show how you will figure out the KM and the Vmax, and the apparent KM and the apparent Vmax (the latter two are in the presence of inhibitor). Also state what type of inhibition this is.
