An allosteric inhibitor of an enzyme acts by
Abinding in the active site in competition with the substrate
Bbinding at a site other than the active site and altering the shape of the active site
Cdestroying the substrate before it reaches the enzyme
Draising the substrate concentration
Answer: B
An allosteric site is separate from the active site. Binding there changes the shape of the active site so the substrate no longer fits or is no longer recognised.
