Allosteric Regulation Generally Results from ____

Question

Allosteric regulation generally results from ____.  
A) excess substrates
B) binding of regulatory molecules at sites other than the active sites
C) a change in the temperature of the system
D) a lack of coenzymes
E) changes in pH

Accepted Answer

Allosteric regulation results from binding of regulatory molecules at sites other than the active sites of the enzyme, which causes a conformational change in the enzyme and affects its activity. It is not a result of excess substrates, temperature change, lack of coenzymes, or changes in pH.
