83. Solving a chemistry problem

55. When determining the catalytic activity of peptidase from the small intestine that hydrolyzes the dipeptide glycylglycine, the following data were obtained:
S, mg 0.2 0.4 0.8 1.2 1.5 2
Product yield, mg/min 2 3.1 4.3 4.95 5.25 5.6
Product yield in the presence of an inhibitor, mg/min 1.2 2 3.1 3.82 4.2 4.67
The inhibitor concentration was 12.3 mg. Using these data, determine the constants of the Michaelis-Menten equation (Km and Vmax) for this drug in the presence and absence of an inhibitor graphically using the Lineweaver-Burk method. Determine the type of inhibition, the inhibition constant
