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.

Students have asked these similar questions
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.
Our human hemoglobin is 100% saturated near the alveoli and 80% saturated after passing through the systemic capillaries and moving back into the veins. By contrast, an extraterrestrial friend's oxygen-binding molecule is 100% saturated near their alveoli and 60% saturated after passing through their systemic arteries and moving back into the veins. How does his hemoglobin compare to yours?
a. they deliver a larger share of oxygen to their tissues at rest
b. the partial pressure of O2 in their alveoli is higher than ours
c. the oxygen- binding molecule in their circulatory system is worse than ours
d. the partial pressure of O2 in their tissue is lower than ours

- As discussed in the Biology and Society section, the delivery of oxygen to muscles is the limiting factor for many athletes. Some athletes seek to improve their athletic performance through blood doping, which can artificially increase athletic capacity. Other athletes achieve the same result by training at high altitude (which promotes the formation of more red blood cells by the bone marrow). If two athletes achieve exactly the same result—one due to injecting her own blood and one due to training at altitude—why do you think the former is considered cheating but the latter is not? What would you do to enforce antidoping rules in sports at all levels (high school, college, Olympic, professional)?arrow_forwardCalculate the average ml of oxygen molecules in 100 ml blood in the athletes at low altitude and then in athletes in high altitude while training at high altitude. Use the following information: 1.39 ml of oxygen per gram of hemoglobin. Do athletes training at high altitudes have more or less oxygen molecules per ml of blood then athletes training at low altitudes? Explain why this difference gives athletes who train at high altitudes an advantage over athletes who train only at low altitudes.arrow_forwardWhich of the following describe(s) a characteristic or function of hemoglobin?a. Hemoglobin consists of four chains of amino acids.b. A hemoglobin molecule contains four iron ions to carry oxygen.c. In addition to transporting oxygen, hemoglobin molecules carry carbon dioxide and hydrogen ions.d. Hemoglobin is a protein found in all formed elements.e. There are four hemoglobin molecules in each red blood cell.arrow_forward

- Can you answer all the parts to this question regarding fish A: Describe countercurrent exchange in your own words. 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_forwardWhich of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?arrow_forwardYou are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively metabolizing muscle tissue, hemoglobin releases oxygen and binds hydrogen ion and, as a result, the pH decreases. Do you agree with her reasoning? Why or why not?arrow_forward
- An 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_forwardWhich of the following is a true statement? A. The concentration of oxygen in water is greater than that in air. B. In animals with gills, ventilation helps to reduce the thickness of the boundary layer. C. Countercurrent flow at the gas-exchange surface results in the diffusion gradient across surface. D. Mammalian lungs requires the diaphragm because the lungs are relatively stiff and filled with parabronchi.arrow_forwardINTERPRET THE DATA Given the makeup of the human body, whatcompound do you think accounts for the high percentage of oxygen?arrow_forward
