Starting with deoxyhemoglobin, describe how the binding of one molecule of O2 to one of its heme groups affects the hemoglobin protein and its function. Also, describe the mechanisms by which CO2 and 2,3-BPG affect hemoglobin function and explain how these effects are important for the physiological functions of organisms that use hemoglobin for carrying oxygen.

Provide the route that one oxygen molecule, O2, will take as it moves from the room air up to its arrival inside the mitochondrion of a cell in a skeletal muscle fiber of the leg. Be detailed, particularly in passing through cell membranes. Write this in flow chart format, using words linked by arrows. Indicate which portion of this route is considered internal respiration, and which portion is considered external respiration.
