Oxygen sensors in the body induce various cell activities to avoid any mismatch between oxygen demand and oxygen supply and to maintain an optimal level of oxygen partial pressure (PO2) in various organs. Oxygen sensing seems to be a well conserved process among procaryontic and eucaryontic cells. The molecular mechanism of oxygen sensing is unknown, but it has been suggested that a hemeprotein is involved that does not participate in the mitochondrial energy production. As examplified on the… CONTINUE READING
