Myoglobin and hemoglobin are oxygen carrying molecules in the human body. Hemoglobin is found inside red blood cells, which ow from the lungs to the muscles through the bloodstream. Myoglobin is found in muscle cells. The function Y=M(p>=Tp calculates the fraction of myoglobin saturated with oxygen at a given pressure p torrs. For example, at a pressure of 1 torr, M(1) = 0.5, which means half of the myoglobin (i.e., 50%) is oxygen saturated. (Note: More precisely, you need to use something called the "partial pressure," but the distinction is not important for this problem.) Likewise, the function 2.3 _F_ 262-5 + \"2.3 calculates the fraction of hemoglobin saturated with oxygen at a given pressure p. (a) The graphs of M03) and H(p) are given below on the domain 0 S p s 100; which is which? Y = H(D) = fraction 1 0.3 0.6 0.4 0.2 20 4o 60 so map 0 M07) is the lower curve. H(p) is the higher curve. 0 M(p) is the higher curve. H(p) is the lower curve. (b) If the pressure in the lungs is 100 torrs, what is the level of oxygen saturation of the hemoglobin in the lungs? (Round your answer to three decimal places.) U (c) The pressure in an active muscle is 10 torrs. What is the level of oxygen saturation of myoglobin in an active muscle?
