In feedback inhibition of a metabolic pathway, where does the inhibitor bind?

A) to the substrate of the first reaction
B) to the product of the first reaction
C) to the enzyme of the first reaction
D) to the enzyme of the last reaction
E) to a substrate or the product of the last reaction

Feedback Inhibition

A regulatory mechanism in which the end product of a metabolic pathway inhibits an upstream process, thus controlling the rate of the pathway.

Metabolic Pathway

A series of chemical reactions occurring within a cell that leads to the conversion of one or more substances into another.

Inhibitor

A substance that slows down or prevents a particular chemical reaction or other processes, such as an enzyme's activity in biochemical reactions.

Final Answer :
C
Explanation :
In feedback inhibition, the inhibitor typically binds to the enzyme of the first reaction in a metabolic pathway, thereby regulating the pathway by preventing the initial step from occurring when the end product is abundant.
