<prompt> True about allosteric enzyme?Single unit enzymeFollows saturation kineticsAllosteric activity is more prominent in the active site of the enzymeHills equation is used to study the kinetics of allosteric enzyme  <response>: Ans. is d i.e., Hills equation is used to study the kinetics of allosteric enzymeAllosteric enzyme is an enzyme in which activity in one subunit affects activity in another subunit. Hence allosteric enzymes are mostly multi subunit enzymes.Most commonly, in an allosteric enzyme, binding of an allosteric regulator to an allosteric site, affects activity in the active site of an enzyme.
