Q. 16.72 - An Introduction to General, Organic, and Biological Chemistry

Question

$16.72$Maltase is an enzyme that hydrolyzes maltose to two glucose molecules. $(16.4)$

$a.$ What are the reactants and products of the reaction?

$b.$Draw an energy diagram for the reaction with and without maltase.

$c.$ How does maltase make the reaction go faster?

Step-by-Step Solution

Answer

  

Maltase is an enzyme that catalyses the hydrolysis of maltose:

Part a) Reactants and products of the reaction

 

part b)

Part c) As the activation energy of the reaction falls, additional reactants join the reaction, and the process accelerates. 

Step 1: Introduction.

                                      --Maltose is the reactant, and two glucose molecules are the result.

Step 2: Given Information (part a).

                          --Maltose is hydrolyzed by Maltase into two glucose molecules.

       are the reaction's reactants and products

Step 3: Explanation (part a).

Reactants and products of the reaction 

$\mathrm{Zn}+2\mathrm{HCl}\to {\mathrm{ZnCl}}_2+{\mathrm{H}}_2$

Step 4: Given Information(part b).

                         -- Maltose is hydrolyzed by Maltase into two glucose molecules.

    a representation of the energy of the reaction with and without maltase

Step 5: Explanation (part b).

 Calculate the reaction's energy with and without maltase. 

Step 6: Given Information (part c).

      

                       Maltose is hydrolyzed by Maltase into two glucose molecules.

   Does maltase speed up the reaction

Step 7: Explanation (part c).

 maltase speed up the reaction ;

                             — Maltose lowers the activation energy needed to convert reactant to product.

                             — As the activation energy of the reaction falls, additional reactants join the reaction, and the process accelerates.
