Is it oxygen, or electrons, that our respiratory system delivers?
by: Gerald H. Pollack

The article proposes a new hypothesis that electrons, rather than oxygen gas, are transferred from the alveoli to the capillaries during respiration. These electrons are theorized to bind to hemoglobin and are then transported to tissues to support metabolism. The hypothesis challenges the traditional understanding of respiration by suggesting a direct role for electrons in the process. Various observations are presented that support this electron transfer theory. If validated, this hypothesis could establish a direct link between respiration and metabolism, potentially transforming our understanding of these processes.
