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.

Release of the products restores the enzyme to its original form. The enzyme can repeat this reaction over and over, as long as substrate molecules are present.
