Which one of the following statements regarding enzyme inhibition is correctA. Competitive inhibition is seen when a substrate competes with an enzyme for binding to an inhbitor proteinB. Competitive inhibition is seen when the substrate and the inhibitor compete for the active site on the enzymeC. Non-competitive inhibition of an enzyme can be overcome by adding large amount of substrateD. Non-competitive inhibitors often bind to the enzyme irreversrbly

Answer» Correct Answer - B
A competitive inhibitor competes with substrate molecule for occupying the active site of an enzyme. These inhibitors have structural resemblance with substrate molecules due to which they easily bind with active site of an enzyme and from an enzyme-inhibitor complex
