Q. An example of feedback inhibition is
A) Cyanide action on cytochrome
B) Sulpha drug on folic acid synthesizer bacteria
C) Allosteric inhibition of hexokinase by glucose 6-phosphate
D) Reaction between succinic dehydrogenase and succinate
Explanation
In feedback inhibition, the product of an enzyme-catalyzed reaction (chain of reactions) accumulates and acts as inhibitor of the reaction, $e.g.,$ $Glucose + ATP\ \overset{\ \ \ Hexokinase\ \ \ }{\rightarrow}\ Glucose - 6 - phosphate + ATP$
