Question
Chapter 34, Problem 9TYU
Summary Introduction
To explain:
The difference between fetal hemoglobin and adult hemoglobin, and its benefits.
Introduction:
Hemoglobin is a metalloprotein (iron + protein) found in RBCs (red blood cells), which provides red color to the RBCs. Hemoglobin helps in the oxygen transportation of the body. One molecule of hemoglobin can carry four molecules of oxygen.

Explain how oxygen is carried in blood, including specifically the role of hemoglobin. Answer the same question with regard to car-bon dioxide transport
Watch this video (http://openstaxcollege.org/l/oxyblood) to see the transport of oxygen from the lungs tothe tissues. Why is oxygenated blood bright red, whereasdeoxygenated blood tends to be more of a purple color?
The hemoglobin of a human fetus differs from adult hemoglobin. Compare the dissociation curves of the two hemoglobins in the graph at right. Describe how they differ, and propose a hypothesis to explain the benefit of this difference.

INTEREPT DATA Look at Figure 46-10b. How would strenuous muscle activity affect the oxygenhemoglobin dissociation curve? (Hint: How does muscular activity affect pH? See Chapter 40 if you need to review this concept.)

B: Describe concurrent exchange in your own words. C: Mammals have dead end sacs called “alveoli” and don’t have the super efficient countercurrent exchange system seen in fish. Why do you think countercurrent exchange is necessary for fish? (hint: think about the difference between where most mammals and fish live).arrow_forward
- Use the image to answer the question. The ability of oxygen to bind hemoglobin changes with altitude as shown. Which statement, if true, BEST explains this observation? A. The partial pressure of atmospheric oxygen decreases with altitude. B. The partial pressure of atmospheric oxygen increases with altitude. C. The partial pressure of atmospheric carbon dioxide decreases with altitude. D. The partial pressure of atmospheric carbon dioxide increases with altitude.arrow_forwardThe reason oxygen diffuses into the tissues seen in internal respiration? a. the temperature differences b. the pressure gradient or difference in partial pressure of oxygen in arterial blood and that in a metabolically active tissue c. the larger the partial pressure of the veins d. .the ability of hemoglobin to bind avidly with oxygenarrow_forwardLike typical fish, the crocodile icefish still need and use oxygen for metabolism. Explain why only fish that evolved to live in cold waters, like the crocodile icefish, could lose hemoglobin? ( unlike terrestrial organisms, marine organisms like fish use oxygen dissolved in water.)arrow_forward
- Describe how hemoglobin functions in the transport ofboth oxygen and carbon dioxide.arrow_forwardAn environment with an oxygen percent of 10% can quickly lead to unconsciousness and death. Assuming that the atmospheric pressure in this environment is 760 mmHg, hypothesize as to why such a low oxygen percent would be hazardous to human survival. Include Dalton’s law of partial pressures and the oxygen-hemoglobin dissociation relationship in your response.arrow_forwardDiscuss why it is advantageous for humans to producedifferent hemoglobins at different stages ofdevelopment.arrow_forward
- Discuss how the transition from water to land of vertebrates gradually changed the respiratory system that even allowed most birds to fly in high altitudes without experiencing hypoxia.arrow_forwardGive an explanation of the relationships between breathing and respiration. Is there a resemblance? Explain why you came to that conclusion.arrow_forwardWhich of the links below are true? a) The cysteine moieties in the beta globulin - nitric oxide transport b) The globe component in hemoglobin - carbon dioxide transport c) The home group in the hemoglobin - oxygen transport d) Carbonic anhydrase - carbon dioxide transportarrow_forward
