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_forwardMatch the descriptor in the left hand column to the type of molecule it describes listed in the right hand column.. Question 4 options: hemoglobin molecule with heme groups containing iron atoms in the reduced state to which carbon monoxide molecules are attached hemoglobin molecule with heme groups containing iron atoms in the reduced state to which oxygen molecules are attached hemoglobin molecule with heme groups containing iron atoms in the oxidized state to which no oxygen molecules can attach hemoglobin molecule with heme groups containing iron atoms in the reduced state to which no oxygen molecules are attached hemoglobin molecule with heme groups containing iron atoms in the reduced state and carbon dioxide molecules attached to amino acid residues of the globin chains 1. carbaminohemoglobin 2. carboxyhemoglobin 3. deoxyhemoglobin 4. methemoglobin 5. oxyhemoblobinarrow_forward
- Write the reversible reaction between hemoglobin and oxygen.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_forwardContrast the structures of the proteins myoglobin and hemoglobin.arrow_forward
- sickle 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_forwardBlood 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_forwardUse the image below to answer this question and the three questions that follow: a) what is the correct description of the hemoglobin for Paul? b) Where is the + pole of the electrophoresis for the gel shown in the previous question? c) Refer to gel illustration above. Which of the following statements provides the best explanation for the difference in mobility of HbA and HbS? 1) HbA is larger in size than HbS 2) HbA is smaller in size than HbS 3) HbA has less negative charge than HbS under electrophoretic conditions used 4) HbA is smaller and more negatively charged under the electrophoretic conditions used 5) HbA is larger and has a less negative charge under the electrophoretic conditions used, whereas HbS is smaller and has a more negative chargearrow_forward
