The process in which a reaction's products inhibit the enzyme that catalyzes the reaction is calledMultiple choice question.negative feedback.positive feedback.selective permeability.enzyme catalysis.

Which statement best describes the principle of feedback inhibition in metabolic regulation?Question 20Answera.The initial enzyme in a pathway is inhibited by the accumulation of its substrateb.The end product of a pathway increases enzyme activity at the beginning of the pathwayc.The final product of a pathway inhibits the action of earlier enzymes in the pathwayd.All enzymes in a pathway are inhibited equally by the final product

For an enzyme to be able to catalyze a reaction, the active site must —Ask Studybuddy (Login to use)Group of answer choicesbe occupied by an inhibitorincrease the activation energy levelhave a complementary shape to the substrateD cause the enzyme to be destroyed in the reaction

A substance that reduces the activity of an enzyme by entering the active site in place of the substrate, whose structure it mimics.Group of answer choicescompetitive inhibitornoncompetitive inhibitor

Noncompetitive inhibition of enzymes occursMultiple Choicewhen a substance other than the correct substrate binds at the active site of an enzyme.when a substance binds to an enzyme at a site away from the active site.by denaturation of an enzyme.by blocking the production of an enzyme.when two enzymes bind together.

Name the inhibition where the end product of the biosynthetic pathway inhibits the activity of the first enzyme.  Competitive inhibition   Feedback repression   Feedback inhibition   Noncompetitive inhibition   Allosteric inhibition
