Document Summary
Looks like vitamin k, therefore acts as a substrate: cannot convert vitamin k, therefore decrease probability of clot forming, cannot convert inactive clotting factors to active clotting factors, hemorrhages (internal bleeding) rat dies. Po2 = 0. 21*760mmhg = 160mmhg: capillaries have low peartial pressure, so it is easier for oxygen to diffuse into tissue. In lungs, oxygen diffuses across the membrane of the alveoli: release of co2 from tissue to bloodstream: co2 + h2o h2co3 h+ + Thalassemias reduction in the synthesis of alpha or beta globin: alpha thalassemia most common in asian populations, beta thalassemia most common in mediterranean population. All of these, as well as sickle cell anemia can result in anemia. Which as the symptoms: fatigue, pale or cold skin, weakness, dizziness. Discussion: in carbon monoide poisoning, co binds to the same site on hemoglobin as oxygen, but with a ~250 times greater affinity (therefore, co preferable than o2).
