Understand competitive and noncompetitive inhibition Practice Test

Substrates formed downstream in a metabolic pathway that act to increase the progression of that metabolic pathway are said to exhibit a                      mechanism.

An antibiotic binds an enzyme, causing it to produce substrate C of a metabolic pathway instead of substrate A of the same pathway. Substrate C ultimately inhibits the enzyme in the normal course of the pathway.

In this metabolic pathway, Substrate C is acting as a(n)                     .
