Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented. Finally, a description of artificial oxygen carriers will be presented. Most of these topics are covered in standard textbooks [6,10,54,113] and monographs on oxygen transport [112].

One hemoglobin molecule has the ability to transport up to 4 oxygen molecules. There are two forms of hemoglobin: oxyhemoglobin, which is saturated with ...
Hemoglobin is found in the red blood cells of the body. Each red blood cell (RBC) contains approximately 280 million hemoglobin molecules (Sears, 1999). The main function of hemoglobin is to transport oxygen from the lungs to the tissues and then transport CO2 back from the tissues to the lungs. One hemoglobin molecule has the ability to transport up to 4 oxygen molecules. There are two forms of hemoglobin: oxyhemoglobin, which is saturated with oxygen molecules and deoxyhemoglobin, which is desaturated with oxygen molecules (Sears, 1999). Oxyhemoglobin has a higher affinity for oxygen than deoxyhemoglobin, and deoxyhemoglobin has a higher affinity for CO2 than oxyhemoglobin. Therefore, oxygen binds to oxyhemoglobin in the lungs and is then transported through the blood stream until it reaches the tissues. There, the oxygen is released to myoglobin, which then transports it to the mitochondria where it is used for aerobic respiration. In exchange, the deoxyhemoglobin picks up 2 protons and 2 molecules of CO2 and returns to the lungs, where the CO2 is released through exhalation (Perutz, 1978).
11. Transport of Oxygen in the Blood | Biology for Majors II - Lumen Learning
Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules.
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.

Nov 13, 2015 · 65,000 g/mol. Explanation: The idea here is that you need to use the ideal gas law equation to determine how many moles of oxygen gas you ...
"65,000 g/mol" The idea here is that you need to use the ideal gas law equation to determine how many moles of oxygen gas you have in that sample. This will allow you to determine how many moles of hemoglobin you have in that "1.00-g" sample. So, the ideal gas law equation looks like this color(blue)(PV = nRT)" ", where P - the pressure of the gas V - the volume it occupies n - the number of moles of gas R - the universal gas constant, usually given as 0.0821("atm" * "L")/("mol" * "K") T - the temperature of the gas, expressed in Kelvin In order to be able to use this equation, you need to have the pressure, volume, and temperature of the sample expressed in the units used for the universal gas constant, R. This means that you will have to convert the volume from mililiters to liters, the temperature from degrees Celsius to Kelvin, and the pressure from kilopascals to Pascals. Rearrange the ideal gas law equation and solve for n, the number of moles of oxygen PV = nRT implies n = (PV)/(RT) n = (99.0/101.325color(red)(cancel(color(black)("atm"))) * 1.60 * 10^(-3)color(red)(cancel(color(black)("L"))))/(0.0821(color(red)(cancel(color(black)("atm"))) * color(red)(cancel(color(black)("L"))))/("mol" * color(red)(cancel(color(black)("K")))) * (273.15 + 37)color(red)(cancel(color(black)("K")))) = 6.14 * 10^(-5)"moles" You know that you need one hemoglobin molecule to bind with four oxygen molecules. This is equivalent to saying that one mole of hemoglobin will bind with four moles of oxygen gas. This means that the amount of oxygen gas you have will need 6.14 * 10^(-5)color(red)(cancel(color(black)("moles O"_2))) * "1 mole hemoglobin"/(4color(red)(cancel(color(black)("moles O"_2)))) = 1.535 * 10^(-5)"moles of hemoglobin" Now, the molar mass of any substance tells you what the mass of one mole of that substance is. In your case, you know that "1.00 g" is the mass of 1.535 * 10^(-6) moles, which means that one mole will have mass of "1.00 g"/(1.535 * 10^(-5)"moles") = 6.5 * 10^4"g/mol" ~~ color(green)("65,000 g/mol") The answer is rounded to two sig figs, the number of sig figs you have for the temperature of the oxygen gas.
