Question
Choose the answer that best describes regulatory enzymes.
Regulatory enzymes are typically composed of multiple subunits.
Regulatory enzymes often catalyze the first committed reaction of a pathway.
Regulatory enzymes often display sigmoidal kinetics.
Regulatory enzymes can be activated and inhibited by allosteric and/or covalent means.
As opposed to non-regulatory enzymes, will operate at various speeds depending on their regulatory status.
All of the above are true.
a.Regulatory enzymes are typically composed of multiple subunits.
b.Regulatory enzymes often catalyze the first committed reaction of a pathway.
c.Regulatory enzymes often display sigmoidal kinetics.
d.Regulatory enzymes can be activated and inhibited by allosteric and/or covalent means.
e.As opposed to non-regulatory enzymes, will operate at various speeds depending on their regulatory status.
f.All of the above are true.
Explanation / Answer
(f) All of the above are true.
Explanation:
Regulatory enzymes regulate a biochemical pathway activity, most often these are regulated by allosteric regulator/inhibitors. They also often catalyze the first committed step (an effectively irreversible enzymatic reaction) in a biochemical pathway.
