Question

Which one of the following statements holds true for the induced-fit model? A) Once the enzyme binds to the specific substrate molecule , no structural changes can occur in the active site in the enzyme . B) Once the enzyme binds to the specific substrate molecule , structural changes can occur in the active site to accommodate the product . C) Once the enzyme binds to a specific substrate molecule , subtle structural changes can occur in the active site , which are reverted when the reaction is over .

Answer 1

The best answer to describe an induced-fit model of an enzyme is option B. For this model, once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accommodate the product. It is a proposed mechanism of interaction between an enzyme and a substrate.
