Question

question 6 (10 points)listen__________ is a mechanism in which the end product of a metabolic pathway inhibits the activity of an enzyme that catalyzes an early step in the pathway.competitive inhibitionallosteric inhibitionnoncompetitive inhibitionfeedback inhibitionquestion 7 (10 points)

Explanation:

• Competitive inhibition involves an inhibitor competing with the substrate for the enzyme's active site, not related to pathway end products inhibiting early steps.
• Allosteric inhibition is when a molecule binds to an enzyme's allosteric site to alter its activity, but this is a broader category, not specifically describing end-product regulation of a metabolic pathway.
• Noncompetitive inhibition is a type of inhibition where the inhibitor binds to a site other than the active site, reducing enzyme activity, but does not refer to pathway end-product feedback.
• Feedback inhibition specifically describes the mechanism where the final product of a metabolic pathway acts to inhibit an enzyme that functions in an early step of the same pathway, matching the definition provided.

Answer:

Feedback inhibition
