Feedback inhibition occurs when end product of a reaction interferes with the enzyme that helped produce it. The inhibitor does this by binding to a second active binding site that's different from the one attached to the initial reactant. The enzyme then changes the shape and can't catalyse the reaction anymore.
So,in feedback inhibition, the inhibitor of the biochemical pathway is often the final product of the biochemical pathway.
Hence, first option is the correct answer for this question.

Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is equal to normal, and as the substrate concentration is increased more and more, the rate of reaction remains the same as the normal rate. What can be concluded about the unknown substance? Select...

Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is slower than normal, but as the substrate concentration is increased more and more, the rate of reaction approaches normal. What can be concluded about the unknown substance? Select the correct answer below: O...

Compare competitive and noncompetitive inhibition Question Suppose that glycerol (CH,OHCH(OH)CH,OH) is a substrate in an enzyme-catalyzed biochemical reaction and propylene glycol (CH OHCH(OH)CHZ) is an inhibitor of the reaction. Would you expect propylene glycol to be a competitive or noncompetitive inhibitor? Why? Select the correct answer below: O It is likely that propylene glycol would be a competitive inhibitor because it easily binds to glycerol. O It is likely that propylene glycol would be a competitive inhibitor because it has...
