Step by step
Solved in 3 steps
- Explain what a partial pressure gradient is and how such gradients figure in gas exchange.Explain the mechanism through which the hemoglobin oxygen dissociation curve changes in exercising tissues relative to those tissues at rest. How does this change affect the amount of oxygen delivered to exercising tissues?The following graph shows partial saturation (Y) of myoglobin (Mb), adult hemoglobin (HbA) and fetal hemoglobin (HbF) as a function of partial oxygen pressure (in mmHg). Use it to answer the question: Fetal hemoglobin ( biological function: HbF) demonstrates lower p50 than adult hemoglobin (HbA). This adaptation has the following A. Allow fetal hemoglobin form pentamer subunits. B. HbF has lower affinity for for O2 compared to adult Hb C. Allow fetal hemoglobin to effectively intercept oxygen from mother's hemoglobin. D. Allow fetal hemoglobin to replace myoglobin in muscles
- Compare and contrast the oxygen binding pockets of myoglobin and haemoglobin.During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungsUnderstand the curve showing oxygen’s affinity for hemoglobin. What factors change hemoglobin’s affinity for O2 and how does the plot of Hb’s O2 saturation change?
- After spending a day or more at high altitude (with an oxygen partial pressure of 75 torr), the concentration of 2,3- bisphosphoglycerate (2,3-BPG) in red blood cells increases. What effect would an increased concentration of 2,3-BPG have on the oxygen-binding curve for hemoglobin? Why would this adaptation be beneficial for functioning well at high altitude?Describe the effects of increased DPG on the oxygen–hemoglobin dissociation curve. What is the adaptive importance of the effect of DPG on the curve?Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 80 mm Hg. Assume hemoglobin is 50% saturated with oxygen at a partial pressure of 24 mm Hg and that the Hill coefficient is 3.
- Graph the relationship between hemoglobin–O2 saturation and the partial pressure of O2 in the blood. What is the functional significance of the shape of the O2–hemoglobin dissociation curve? What factors affect the shape of the curve?During exercise, the oxy-hemoglobin curve shifts to the right, describe the causes of this and why it occursWhen we change altitude, during the next few days, the body responds by adjusting Hb cooperativity. This can be accomplished by changing the concentration of 2,3-BPG in the blood. After moving from a low altitude to a higher altitude, does 2,3,-BPG increase or decrease? Explain how this affects oxygen transport capacity
