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

Which of the following is true regarding competitive and noncompetitive inhibition?

I. Both can be overcome by increasing the substrate concentration

II. Competitive inhibition induces changes to the active site

III. Noncompetitive inhibition has no effect on the enzyme affinity for substrates

You are reading about the functions of a unique chemical compound. This compound works on enzymes throughout the body by altering the shape of the enzyme without blocking the active site. This compound functions via which mechanism?

If an antibiotic binds the active site of an enzyme but does not change the structure of that enzyme, once removed, the enzyme returns to normal function. In this case, the antibiotic is acting via what enzyme interaction?

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) __________.
