When an enzyme is competitively inhibited, which of the following changes occur?

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.
