Study the given data and answer the questions that follow.
A sample of an enzyme called lactase was isolated from the intestinal lining of a calf. Assays were undertaken to evaluate the activity of the enzyme sample.
The substrate of lactase is the disaccharide lactose. Lactase breaks a lactose molecule in two, producing a glucose molecule and a galactose molecule.
Two assays were carried out.
`{:("Lactose concentration (% w/v)",15,15,15,15,15,15),("Concentration of enzyme smaple (%v/v)",0,5,10,15,20,25),("Reaction rate "mu"mole glucose "sec^(-1)mL^(-1),0,25,50,75,100,125):}`
`{:("Lactose concentration (% w/v)",0,5,10,15,25,30),("Concentration of enzyme smaple (%v/v)",5,5,5,5,5,5),("Reaction rate "mu"mole glucose "sec^(-1)mL^(-1),0,15,25,35,40,40):}`
Which of the following assays would you expect to have the highest reaction rate ?

Options

A. `{:("Lactose concentration (%w/v)","Concentration of enzyme sample (%v/v)"2),(" "15, " "5):}`
B. `{:("Lactose concentration (%w/v)","Concentration of enzyme sample (%v/v)"2),(" "30, " "5):}`
C. `{:("Lactose concentration (%w/v)","Concentration of enzyme sample (%v/v)"2),(" "15, " "25):}`
D. `{:("Lactose concentration (%w/v)","Concentration of enzyme sample (%v/v)"2),(" "30, " "25):}`

Answer

C
