a) Oxygen is absorbed from the lungs into red blood cells where it is bound to hemoglobin and transported throughout the body. The concentration of oxygen in blood is approximately 100 mM. Now imagine that the blood is replaced by pure water. Given that the total pressure within the lungs is approximately 1 bar, and that the oxygen in the atmosphere equilibrates with this new "blood", what would be the concentration of oxygen in "blood"? Show all work. b) Imagine the Mars rover actually finds liquid water on the surface of Mars. The rover analyzes the water and finds that the water contains a 0.002M concentration of dissolved oxygen gas. What is the partial pressure of oxygen gas in the Martian atmosphere?

Transcribed Image Text:a) Oxygen is absorbed from the lungs into red blood cells where it is bound to
hemoglobin and transported throughout the body. The concentration of oxygen in blood
is approximately 100 mM. Now imagine that the blood is replaced by pure water.
Given that the total pressure within the lungs is approximately 1 bar, and that the oxygen
in the atmosphere equilibrates with this new “blood", what would be the concentration of
oxygen in “blood"? Show all work.
b) Imagine the Mars rover actually finds liquid water on the surface of Mars. The rover
analyzes the water and finds that the water contains a 0.002M concentration of dissolved
oxygen gas. What is the partial pressure of oxygen gas in the Martian atmosphere?
