Hemoglobin and the bicarbonate ion act at in the erythrocyt

Hemoglobin and the bicarbonate ion act at ____ in the erythrocyte. ____ 96 of the carbon dioxide generated will bind to water in the erythrocyte. ____ % will bind toe water in the plasma. % will be exhaled. It is rather difficult to breathe at the top of a mountain. Many people attribute this to be due to a lack of air at the top of the mountain. While this is true to a certain degree, the MAIN reason why it is difficult to breathe at the top of the mountain is due to a lack of Based on the information in this chapter, it should be evident that the chloride ion is rather important. Research to determine a normal blood concentration of chloride ions. Be sure to cite your source.

Solution

Answers:

6. Correct

Hemoglobin together with the bicarbonate ions acts as buffer. HCO₃^- enters plasma as buffer.

7. Correct

Process of picking up CO₂ at systemic tissues:

At systemic tissues: systemic tissues to plasma

a. CO₂ diffusion from cells into plasma.
b. 7% CO₂ remains dissolved in plasma
c. CO₂ diffusion from plasma into RBC
d. 23% CO₂ is bound to Hb and makes carbaminohemoglobin (This is exhaled out)
e. 70% is converted to bicarbonate (HCO₃^-)
f. HCO₃^- exits RBC to plasma through chloride shift

8. Correct

Lungs have to work harder to inhale the thinner air. As the air pressure (partial pressure of air, meaning less oxygen) decreases because of altitude, the air has less density. So, we need to inhale more times to get the same volume of air as at sea level. Less air density also means less oxygen.

10. Correct

When the body receives more oxygen than it needs, the result can lead to a condition known as respiratory alkalosis (high pH). One of the most common cause is hyperventilating. The point of breathing into a bag is to re-breathe the exhaled carbon dioxide (CO₂) in the hopes of bringing the body back to a normal pH level.
