Some of the statements regarding competitive inhibition are given below

a)  The effect of a competitive inhibitor depends on the inhibitor concentration, the substrate       concentration and the relative affinities of the substrate and the inhibitor for the enzyme.

b) if the substrate concentration is low, the degree of inhibition will be great.

c) the substrate concentration is high, then the degree of inhibition will be marked low

d) non-competitive inhibitor can combine with an enzyme molecule to produce a dead-end complex
