<prompt> When an enzyme is competitively inhibited, which of the following changes occur?The apparent Km is unchanged.The apparent Km is decreased.Vmax is decreased.Vmax is unchanged.  <response>: Features of noncompetitive inhibition:Inhibitor have no structural resemblance to substrate.Most irreversible Except a few reversible non-competitive inhibition.Excess substrate do not abolish the inhibition.Km remains the same.Vmax decreases. Features of competitive inhibition:Inhibitor will be structural analogue of substrate.Reversible Excess substrate abolish the inhibition.Km increases.Vmax remains the same.
