Question Video: Applying Knowledge of Enzymes to Explain ...

Each enzyme has an area called an active site, which is specifically shaped to fit the substrate like a lock and a key fit together. This is called the lock-and-key model. First, a substrate molecule binds to the active site of the enzyme, which forms an enzyme–substrate complex. As the reaction completes, the enzyme releases the product. Since a bond was broken in this …

Enzymes: principles and biotechnological applications

15.11.2015·Allosteric enzymes have an initially low affinity for the substrate, but when a single substrate molecule binds, this may break some bonds within the enzyme and thereby change the shape of the protein such that the remaining active sites are able to bind with a higher affinity. Therefore allosteric enzymes are often described as moving from a tensed state or T …

competing with the substrate for the active site of the enzyme. Once the inhibitor gets into the active site it stays there as it is not broken down. This means those enzymes that bind with the inhibitor are no longer available to bind with the substrate. Sometimes competitive inhibition is an important way of controlling the bodies reactions to prevent over stimulation. Some …
