Question
Chapter 34.3, Problem 1TC
Summary Introduction
To answer:
Why is oxygen-rich blood depicted as red and oxygen-poor blood as blue?
Introduction:
Hemoglobin is the oxygen-carrying pigment and predominant protein present in the red blood cells. It forms an unstable, reversible bond with oxygen. When Hemoglobin in its oxygenated states it is bright red in color. In the reduced state, it is purple-blue in color.

- Hemoglobin will bind oxygen and release CO2 in places where there is a higher concentration of O2, lower concentration of CO2, lower temperature and lower acidity (as it is in lungs) and will do the reverse – release oxygen and bind CO2 - in places where there is a lower concentration of O2, higher concentration of CO2, higher temperature and higher acidity (as it is in working muscles). True False While white blood cells never leave the circulation, red blood cells regularly leave it and travel by lymphatic system or find home in other tissues, e.g., lymph nodes, spleen, etc. True False Blood clotting (coagulation) is a complex process involving many factors and it exhibits positive feedback loops: many of the factors also stimulate production of their own precursors.

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.
