Question

23) Daring a laboratoury experiment, you discover that an enzyme-catalyzed raction a n / an enzyme-catalyzed reaction has a AG of-20 kcal/mol. 51 you double the amount of enzyme in the reaction, what will be the AG for the new rehicinio 3)-20 kcalimol C 0 kcal/mol D) +20 kcal/mol 24) According to the induced fit hypothesis of enzyme catalysis, A) the binding of the substrate depends on the shape of the active s B) some enaymes change their structure when activators bind to the enzyme C) the binding of the substrate changes the shape of the enzyme's active site D) the active site creates a microenvironment ideal for the reaction 25) A noncompetitive inhibitor decreases the rate of an enzyme reaction by A) binding at the active site of the enzyme B) changing the shape of the enzyme's active site C) changing the free energy change of the reaction

Explanation / Answer

23) option D (+20 kcal/mol)

the gibbs energy is the overall energy released during the reaction and is the energy difference between the product and substrate. So it remains same for every reaction while gibbs free energy is lowered with more enzymatic action.

24) option C

25) option B.

The non competitive inhibitor also changes the conformation of the enzyme along with the enzyme's active site.
