How does oxygen function in metabolism?

While the provision of energy for metabolism is primarily an oxidation process, that process takes many small steps in cellular respiration. With the use of four protons and four electrons, the oxygen molecule is converted to two molecules of water. …

Does oxygen increase metabolism?

When the oxygen level is low, one of the proteins (HIF-1alpha) turns on certain genes, including the erythropoietin gene, to increase the production of erythropoietin. The hormone, in turn, increases the oxygen availability by boosting the production of red blood cells.

How does lack of oxygen affect cells?

When oxygen levels are 0.5–3% (hypoxia), cells do not undergo apoptosis. Instead, hypoxia activates a variety of cellular events that ultimately lead to cell survival. Low oxygen triggers signal-transduction pathways involved in both cell death and survival (Fig. 1).
