Close Explanation
A competitive inhibitor binds to the enzyme’s active site, and slows down the process.

ExplanationClose
The substrate will soon find an active site. The effect of a competitive inhibitor is to slow down the process.

Close Explanation
The shape of the active site changes because the non-competitive inhibitor has bound to an allosteric site; so preventing an enzyme-substrate complex from forming.

Close Explanation
The reaction rate cannot reach the same point because the non-competitive inhibitors have changed the shape of some of the active sites.
