Question
Chapter 42, Problem 10TYU
Summary Introduction
To explain: The differences between fetal hemoglobin and adult hemoglobin.
Concept introduction:
Respiratory system exhibits a catabolic process. It mainly involves the exchange of gases between oxygen and carbon dioxide. In the exchange process, the respiratory pigments play a keyrole in gaseous exchange. Example: hemoglobin.

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.
Calculate 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.
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

- Creat a Concept map about “The Respiratory and Circulatory systems” Include a minumun of 20 concept “bubbles” and also include a minimum 20 arrow or symbols. Includes at least 3 of these “subtopics” that branch from your central idea (Gas Exchange, Transport, Respiration, Circulation, Breathing Mechanics, Lymphatic System, Components of Blood, Spirometry, Immunity, Regulation, Blood Pressure, Homeostasis)arrow_forwardAs 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_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
