Answer #1

B.inactivates an enzyme by binding to the allosteric site of an enzyme and changing the shape of the active site.

EXPLANATION:

In non competitive inhibition enzyme can bind to both substrate and inhibitor where as in competitive inhibition its impossible and in that case competitive inhibitor binds to the active site of the enzyme and block the substrate.A non competitive inhibitor binds to allosteric site ,which is not an active site of the enzyme and changes the structure of enzyme ie.,changing the shape of active site.hence it blocks the enzyme from binding to substrate and it leads to inactivation of enzyme.

    Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
