Which one of the following statements holds true for the induced-fit model?

Once the enzyme binds to the specific substrate molecule, no structural changes can occur in the active site of the enzyme.

Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accomodate the product.

Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.

which one do you think it is? Any ideas?

In the induced fit model, `when an enzyme binds to the appropriate substrate, subtle changes in the active site occur. This alteration of the active site is known as an induced fit. Induced fit enhances catalysis, as the enzyme converts substrate to product.` By definition an enzyme is a biological catalysts and catalysts remain unchanged by the end of the process I got the above definition from this website ` http://www.phschool.com/science/biology_place/labbench/lab2/induced.html ` Check it out. It has a really cool graphical demonstration of the process, which should help you remember it next time.
