Provide two examples where enzymes alter their conformation to prevent unwanted side reactions. Briefly in one to three sentences, state what it prevents and how it does it    2

The site where a noncompetitive inhibitor binds to an enzyme is called: Active site Receptor site Coenzyme O Allosteric site Enzyme linked receptors:

Briefly explain the process of enzyme reaction (in one sentence).

Complete the sentences below using information from the viewer.These six amino acid residues are split between two subunits. Together, they form an (acidic/basic) tunnel that appears to connect the two active sites. Mutation of several of these residues to Ala results in a significant decrease in the decarboxylation activity of the enzyme. Researchers propose that this region may be important for  proton shuttling between the two active sites to ensure that only one is catalytically active at a time.
