Chapter 10, Problem 18QP
Summary Introduction
To explain: The quaternary structure of the blood protein hemoglobin.
Introduction: Hemoglobin is a protein molecule that is found in red blood cells. It contains iron that helps in transferring oxygen dissolved in blood from one location to another inside the body. The presence of the adequate amount of hemoglobin in blood is very important to deliver oxygen to all parts of a body. The lack of hemoglobin can cause oxygen deficiency in different parts of the body.

The isolated α subunit binds oxygen, but the O2 -saturation curve ishyperbolic rather than sigmoid. In addition, the binding of oxygen to the isolated α subunit is not affected by the presence of H+, CO2 , or BPG. What do these observations indicate about the source of the cooperativity in hemoglobin?arrow_forwardDiscuss the structure and function of hemoglobin, as well as its breakdown products?arrow_forward
