Question

The figure given below shows three velocity-substrate concentration curves for an enzyme reaction. What do the curve a, b and c depict respectively

• A. a = Enzyme with an allosteric modulator added, b = Normal enzyme activity c = competitive inhibition
• B. a = Normal enzyme reaction b = Competitive inhibition c = Non-competitive inhibition
• C. a = Enzyme with an allosteric stimulator b = competitive inhibition added c = normal enzyme reaction
• D. a = Normal enzyme reaction b = Non-competitive inhibitor added c = Allosteric inhibitor added.

Answer 1

The correct option is B

a = Normal enzyme reaction

b = Competitive inhibition

c = Non-competitive inhibition

a, b and c in the given curves show normal enzyme reaction, competitive and non-competitive inhibitions respectively.
