If hemoglobin saturation is kept above _______%, the PO2 can change a lot with minimal change in saturation.
Homework Answers
Ans) > 80%
Explaination:
As the PO2 decreases, the percentage of saturated hemoglobin also decreases. The oxygen-hemoglobin dissociation curve has a sigmoidal shape due to the binding nature of hemoglobin. With each oxygen molecule bound, hemoglobin undergoes a conformational change to allow subsequent oxygens to bind.
- A level of 80-100 is considered normal. 60-80 is considered mild hypoxemia, or mildly low blood oxygen level. Anything greater than 60 is often considered acceptable.

Draw a diagram that shows the saturation of the two proteins hemoglobin and myoglobin as a function of the oxygen pressure. Use that diagram to describe how these characteristics of these two proteins allow oxygen to be taken up by hemoglobin from the air, and passed on to myoglobin. Describe how the increased concentration of carbon dioxide in heavily exercising muscle tissue can improve the transport of oxygen to myoglobin.

Which of the following is NOT an indication that the binding of oxygen to hemoglobin is cooperative? a. Oxygen binding of one subunit induces a shift of the other hemoglobin subunits from the T state to the R state. b. A plot of hemoglobin’s fractional saturation against partial pressure of oxygen (Y versus pO2), is sigmoidal rather than hyperbolic. c.Hemoglobin has four subunits, each of which can bind oxygen. d.The Hill coefficient, n, is greater than 1.0.

Draw three separate oxygen-hemoglobin dissociation curves and then use arrows to show the change in oxygen saturation of most hemoglobins when: 1. deoxygenated blood enters the capillaries in the lungs. 2. oxygenated blood enters the capillaries in muscle tissue at rest. 3. oxygenated blood enters the capillaries in muscle tissue during vigorous exercise.

In plain language, describe what the oxygen-hemoglobin
dissociation curve shows. Under normal conditions, the curve can
shift to the right and left. A right shift can be induced by
increased temperature and lower pH among other things. Describe
what a right shift means in terms of hemoglobin’s relationship to
oxygen. In your answer, be sure you address what is actually
happening at the level of the protein (hemoglobin is a protein).

If your levels of either of Hemoglobin and Hematocrit are low or high, how can you interpret that? Does it indicate that you are at risk for or may have any conditions or diseases? How can you change your diet or other lifestyle factors to bring these level(s) into the normal range?
