The concentrations of lactate in blood plasma before, during, and after a 400 m sprint are shown in the graph.(a) What causes the rapid rise in lactate concentration?(b) What causes the decline in lactate concentration after completion of the sprint? Why does the decline occur more slowly than the increase?(c) Why is the concentration of lactate not zero during the resting state?
Define the Significance of HMP shunt pathway ?
a) How much more O2 can be transported by the blood when erythrocytesleave the lungs? Consider that a normal adult has a concentration of 15 g hemoglobin/100 mL of bloodand that the hemoglobin is 98% saturated with O2 at the usual pO2 of 100 torr in the lung at sea level.
b) On the basis of the graph, explain how myoglobin facilitates the diffusion of O2 through muscle cells. Would myoglobin be effective as an O2-transport protein in cells of other tissues? Explain.

Some blood from the athlete is removed well before competition, and then transfused back into the athlete just before competition. (a) Why might blood transfusion benefit the athlete? (b) With time, stored red blood cells become depleted in 2,3-BPG. What might be the consequences of using such blood for a blood transfusion?arrow_forwardFrom the figure of O2 binding to myoglobin and hemoglobin (ignore the linemarked as T) as described in lecture (shown below) answer the following questions. a) Estimate the P50 for myoglobin from the plot. Show how this estimation isdetermined from the binding curve above. ( The first ghraph) b)Using YO2 = PO2/P50 + PO2 , calculate the fraction of O2 bound for myoglobin at 1 torr. (2nd graph) c)Using the binding curve on the previous page, show how you can estimate whatfraction of hemoglobin is bound near tissues at a pO2 of 30 torr and provide this value. If the pH were lowered, will the amount of O2 bound to hemoglobin at 30 torr increaseor decrease? Explain why this is so based on how this changes hemoglobin structure. If 2,3-BPG were added to the solution, will the amount of O2 bound to hemoglobin at30 torr increase or decrease? Explain why this is so based on how this changes hemoglobinstructure.arrow_forward
