C)are not affected by temperature or pH.
D)have two active sites.
E)all of these.

Question

Quizplus · Accepted Answer

Allosteric enzymes have active sites where substrate molecules bind, but they also have other sites that can bind with inhibitor or activator molecules, affecting the enzyme's activity. The other options are not accurate - while some allosteric enzymes may be associated with energy-carrying nucleotides, this is not a defining characteristic of allosteric enzymes as a whole, and allosteric enzymes can certainly be affected by temperature and pH. Additionally, not all allosteric enzymes have two active sites - some may have multiple allosteric sites without multiple active sites.
