Anoncompetitive inhibitor . binds to the active site of an enzyme a. b. increases the rate of enzyme action alters the primary structure of the enzyme c. d. none of these

 D. none of these

Explanation:  A non competitive inhibitor is the one that binds to the enzyme away from the active site.

It changes the conformaion of the enzyme as well as that of the active site.

It does not increases the rate of the enzyme action.

It doesnot alter the primary structure of the enzyme.

Thus the given options for the non reversible inhibitor are not the correct ones.

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
