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 induced-fit model is an elobaration of lock and key model and it says that
Once the enzyme binds to the specific substrate molecule , structural changes can occur in the active site to accommodate the product
when a substrate react with a enzyme it causes chemical changes and bond whether lengthen or shorter and change the shape
so i think option B is correct
hope it helps
