In an experiment involving an enzyme, the ph is raised from 2 to 11. what will be the most likely effect of this on the reaction?

Answer;

-enzyme will denature, stopping the reaction

-Explanation;

In an experiment involving an enzyme, the effect of raising pH from 2 to 11 will be the denaturation of the enzyme and consequently stopping the reaction.

Enzymes work at a certain pH, called optimum pH, increasing the pH of an enzyme above the optimum pH affects the structure of an enzyme through denaturation and thus affecting its activity. When this happens the enzyme looses the ability to catalyze the reaction and therefore, the reaction will stop.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
