The ability to monitor oxygen (O2) availability and delivery is crucial to an animal's survival. Vertebrates have a number of O2 'sensing' cells that monitor environmental oxygen and ensure adequate delivery to the tissues. While there is little doubt that these cells perform important homeostatic functions, there is little consensus on how a change in O2 concentration, or partial pressure (pO2), is transduced into a physiological response. We recently proposed that the metabolism of hydrogen… CONTINUE READING
