Question

In lock and key model, the enzyme catalyzed reaction may produce an adverse reaction.

(a) True

(b) False

This question was addressed to me by my college director while I was bunking the class.

The origin of the question is Enzyme Kinetics topic in section Enzyme Kinetics of Enzyme Technology

Answer 1

Right answer is (a) True

For explanation: The lock and key model represents that as a key fits into a lock, the substrate in the same way binds to active site of the enzyme producing required products. In this model, the catalytic site is freely accessible. Thus any other compound can also interact with the active site and produce an adverse reaction. Hence the statement.
