An enzyme-catalyzed reaction produces a product that has a maximum absorbance at 412 nm. The extinction coefficient is 4000 M-1 cm-1. A 10/1 dilution of the enzyme is made and 20 μL of the dilution are put into a cuvette with 80 μL of water and 1.9 mL of reaction cocktail. The absorbance change per minute is 0.05. Show your calculations for full credit.
a. How many units were in the cuvette if 1 unit = 1 μmol/min? (3)
b. How many units were in the cuvette if 1 unit = 1 nmol/min? (3)
c. What is the relative activity of the undiluted enzyme (1 unit = 1 μmol/min)?

Consider the enzyme-catalyzed reaction with Vmax=164 (μmol/L)min−1 and KM=32μmol/L. Part A If the total enzyme concentration was 6 nmol/L, how many molecules of substrate can a molecule of enzyme process in each minute? Express your answer to three significant figures. kcat kcat = 2.73×104 min−1 Part B Calculate kcat/KM for the enzyme reaction.

You have a 25 ml enzyme sample that has a total of 100 micro-moles/min of activity If you were to assay the enzyme, how much of it would you need in your assay in order to get an absorbance of 0.50 in a 30-minute assay. The product E=13,800M-1cm-1 and you are using a standard 1mL cuvette Beer-lambert law: A=CIE I=1
