Chapter 8, Problem 3RQ
Summary Introduction
To determine: The missing labels to the given diagram of hemoglobin and mention the factors that affect the affinity of hemoglobin to bind with oxygen.
Introduction: Hematologic system comprises blood, blood vessels, and blood-forming organs. Blood is a fluid connective tissue that carries oxygen, glucose, and nutrients throughout the body. It mainly consists of four types of components, namely red blood cells (RBCs), white blood cells (WBCs), plasma, and platelets.

- What is oxyhemoglobin? Where does it form?arrow_forwardI am eating a snack as I type this question. My body is breaking down the food to provide energy so that my muscles will continue to contract and I can continue to type. During this process, some acidic byproduct could be produced, decreasing the the pH in my muscles. a) What effect will this have on the structure of hemoglobin. (Briefly describe. No more than 2-3 sentences.) b) What effect does this have on the Pso of hemoglobin?arrow_forwardIn addition to O2 binding, changes in other chemical conditions can result in changes in hemoglobin structure and function. Increases in blood H+ result in oxygen binding curves for hemoglobin that are shifted to the right. The effect of H+ can be understood in terms of the equilibrium:H-Hb+ + O2 → Hb-O2 + H+How does the difference in pH in the lungs and tissues help hemoglobin do its job of delivering oxygen? Use the equilibrium equation in your argument.arrow_forward
- Blood in our body changes color as a function of its oxygenation state. Given the spectral data below, calculate the absorbance of red light (600 nm) of fully oxygenated and deoxygenated blood. Using this data, determine what percentage of red light would go through a sample of blood that is 50% oxygenated. Assume the patient has a hemoglobin concentration of 10 mM and pathlength of 1 cm.arrow_forwardsickle cell disease and its variants are genetic disorders resulting from the presence of a mutated form of hemoglobin . propose a proper therapeutic strategy to ameliorate or cure this disease.arrow_forwardMyelodysplastic syndrome is a genetic abnormality that disrupts the ability of red blood cells (erythrocytes) to produce hemoglobin.

If you Google the number of hemoglobin molecules in a RBC, most sources state 250-270 million hemoglobin molecules. If hemoglobin has a molecular weight of 67,000 Da, what is the concentration of hemoglobin in RBCs? Show your work and show your units. Use dimensional analysis to have your final answer in moles per liter. B) The hemoglobin molecule is nearly spherical with a diameter of 55 Angstroms.
