Allosteric regulation controls reaction rate by ____.
A)producing excess substrates
B)binding regulatory molecules at a site other than the active site
C)changing in the temperature of the system
D)binding regulatory molecules to the active site
E)alternately oxidizing and reducing the substrate

Question

Quizplus · Accepted Answer

Allosteric regulation involves binding of regulatory molecules at a specific site on the enzyme, called the allosteric site, which is different from the active site. This binding can either activate or inhibit the enzyme, thereby controlling the rate of the reaction. The other choices mentioned (producing excess substrates, changing in the temperature of the system, binding regulatory molecules to the active site, alternately oxidizing and reducing the substrate) are not related to allosteric regulation.
