The presence of a noncompetitive inhibitor:

0 leads to a decrease in Km and V

o increases the steady-state concentration of the enzyme substrate complex [ES].Э

leads to an increase in Km without affecting V max·

0 leads to both, an increase in the Vmax of a reaction and an increase in the Km·

0 leads toa decrease in the observed Vmax·

Answer #1

Ans. Lead to a decrease in observed Vmax.

Non-competitive inhibitors don't compete with [S] for active site but bind to substrate to site other than active site. So Km remains unchanged. And V​​​​​max is decreased.

Km is a measure of affinity of enzyme for its substrate.

Which of the following statement concerning enzyme-catalyzed reactions is CORRECT? The rate of an enzyme catalyzed reaction is independent of substrate concentration. At saturating levels of substrate, the rate of an enzyme –catalyzed reaction is proportional to the enzyme concentration. The Km for a regulatory enzyme varies with enzyme concentration. If enough substrate is added, the normal Vmax of an enzyme –catalyzed reaction can be attained even in the presence of a noncompetitive inhibitor. The sigmoidal shape of the v-versus...
