In active cells, pO_2 may be 10 torr at the cell surface and 1 torr at the mitochondria (the organelles where oxidative metabolism occurs).
A) How does myoglobin (p_50 = 2.8 torr, where p_50 is the partial pressure of oxygen required to 50% saturate myoglobin) facilitate the diffusion of O_2 through these cells? (Myoglobin does not just pick up the O_2 at the cell membrane and carry it over to the mitochondrial membrane.)
B) Active muscles consume O_2 much faster than do other tissues. Would myoglobin also be an effective O_2 - transport protein in other tissues? Explain.
