Summary Introduction
To review:
The variable responsible for lowering the pH level in metabolically active cells that causes the release of oxygen from the red blood cells (RBCs).
Introduction:
RBC is the cellular component of blood, which is responsible for carrying oxygen from lungs and supplies it to the body cells. Oxygen is the key ingredient that is required for the

- I 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_forwarda) Hemoglobin accounts for 95% of the protein in red blood cells. 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. You can look at the 3D structure of human hemoglobin on the RCSB PDB website. Calculate the volume of a hemoglobin molecule, and can the number of hemoglobin molecules quoted in Question a actually fit into one red blood cell?arrow_forwardHemoglobin 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. B lymphocytes mature in the thymus while T lymphocytes mature in the bone marrow True False Antibodies are molecules on the surfaces of foreign…arrow_forward
