Question

what does copper ii sulfate do to the enzyme activity using potato liquid. how do you explain this change?

Answer 1

Copper(||)sulphate is a noncompetitive inhibitor.it can bind to the enzymes which are present in potato liquid with or without a substrate at different places at the same time.it changes the conformation of an enzyme as well as its active site which make the substrate unable to bind to the enzyme effectively.so the copper (||) sulphate distorts the overall shape of the enzyme .so the effeciency decrease.the catecholase enzyme is present in potato liquid which efficiency decrease by copper(||) sulphate .because copper (||) sulphate as a noncompetitive inhibitor distorts the overall shape of the enzyme.non competitive inhibitors are usually reversible,but are not influenced by the concentration of the substrate.
