Question 58

Multiple Choice

Exhibit 6A This is a reaction going on in your muscle cells right this very minute: Exhibit 6A This is a reaction going on in your muscle cells right this very minute:   The enzyme triose phosphate isomerase catalyzes this reaction in the forward direction as part of the glycolytic pathway. It follows simple Michaelis-Menten kinetics:   Typical cellular concentrations: triose phosphate isomerase = 0.1 nM Dihydroxyacetone phosphate = 5 µM glyceraldehyde-3-phosphate = 2 µM Refer to Exhibit 6A.  Restrainin  is an inhibitor of triose phosphate isomerase. When it is added to cells at a concentration of 0.4 nM, the enzyme's apparent K<sub>M</sub> for the substrate is altered to 100 µM, but the V<sub>max</sub> is unchanged. A)  This is a competitive inhibitor. B)  This is an uncompetitive inhibitor. C)  This is a noncompetitive inhibitor. D)  This is an irreversible inhibitor.
