Competitive inhibitor Uncompetitive inhibitor Allosteric inhibition Hemoglobin is a protein that is responsible for delivering oxygen to the body’s tissues. Thus, hemoglobin has an oxygen binding site that serves as its “active site,” though it is not a enzyme. Another molecule, 2,3-BPG binds to another site on hemoglobin, and is able to make it so hemoglobin cannot bind oxygen as it normally would. Which of the following best describes the role of 2,3-BPG? Competitive inhibitor Uncompetitive inhibitor Allosteric inhibition Allosteric activator
