- which of the following forms all matter?What is a bivalent?When deoxyhemoglobin was first isolated in crystalline form, the researcher who did so noted that the crystals changed color from purple to red and also changed shape as he observed them under a microscope. What is happening on the molecular level? Hint: The crystals were mounted on a microscope slide with a loosely fitting cover slip.
- What is a mixture?Hemoglobin is composed of which two types of polypeptide chains, alpha?Hemoglobin is the oxygen-carrying molecule of red blood cells, consisting of a protein and a nonprotein sub- stance. The nonprotein substance is called heme. A sample of heme weighing 35.2 mg contains 3.19 mg of iron. If a heme molecule contains one atom of iron, what is the molecular weight of heme?
- White blod cell concentration in normal blood is approx 12,000 cells/mm^3. How many white blood cells does a normal adult with 5.0L of blood have? Express answer in scientific notation.Hemoglobin is 6.0% heme (C₃₄H₃₂FeN₄O₄) by mass. Toremove the heme, hemoglobin is treated with acetic acid andNaCl to form hemin (C₃₄H₃₂N₄O₄FeCl). At a crime scene, ablood sample contains 0.65 g of hemoglobin. (a) How manygrams of heme are in the sample? (b) How many moles of heme?(c) How many grams of Fe? (d) How many grams of hemincould be formed for a forensic chemist to measure?What exactly happens in hemoglobinopathy and what is sickle cell anemia? How are these related to the structure of proteins in our body?
- a typical human contains between 9 and 12 pints of blood. A woman's body contains 10.01 pints of blood and the density of hemoglobin in her body is 13.5g/dL. What is the mass in grams of haemoglobin that would be found in 10.01 pints of blood ( 1 gallon=3.785L, 1 gallon=8 pints).Jeff's body contains about 5.26L of blood that has a density of 1060 kg/m. Approximately 45.0% (by mass) of the blood is cells and the rest is plasma. The density of blood cells is approximately 1125 kg/m, and about 1% of the cells are white blood cells, the rest being red blood cells. The red blood cells are about 7.50 µm across (modeled as spheres). What is the mass of the blood mblood in Jeff's body? kg mblood = Approximately how many blood cells (of both types) N are in Jeff's blood? blood cells N =A typical human body contains between 9 and 12 pints of blood.
