The enzyme chymotrypsin catalyzes the hydrolysis of a peptide containing phenylalanine. Using the data below at a given temperature, calculate the maximum rate of the reaction, Ratemax. Interpretation Introduction

Interpretation:

Using the given data the maximum rate for the given reaction should be calculated.

Concept introduction:

Maximum reaction rate: It is obtained by plotting inverse of concentration of the reactant with the inverse of respective rate, the point where inverse of concentration becomes 0 is the point of inverse of maximum rate which is then reversed in order to obtain the maximum rate.

Explanation

The maximum rate is obtained plotting inverse of concentration of the reactant with the inverse of respective rate, the point where inverse of concentration becomes 0 is the point of inverse of maximum rate which is then reversed in order to obtain the maximum rate.

The given concentration data of peptide should be inversed then similarly the given set of rate data also should inversed resulting to given the new table as follows,

1/(Concentration)1/(Rate)40004.55×10520002.63×10510001.69×1055001.41×105

Plotting the above values gives rise to the following graph
