Phosphorylation
In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion.[1] This process and its inverse, dephosphorylation, are common in biology.[2] Protein phosphorylation often activates (or deactivates) many enzymes.[3][4] During respiration and photosynthesis Phosphorylation is essential to the processes of both anaerobic and aerobic respiration, which involve the production of adenosine triphosphate (ATP), the “high-energy” exchange medium in the cell. During aerobic respiration, ATP is synthesized…

Carotid body glomus cells mediate essential reflex responses to arterial blood hypoxia
Glomus cells are the cell type mainly located in the carotid bodies and aortic bodies. Glomus type I cells are peripheral chemoreceptors which sense the oxygen, carbon dioxide and pH levels of the blood. When there is a decrease in the blood’s pH, a decrease in oxygen (pO2), or an increase in carbon dioxide (pCO2), the carotid bodies and the aortic bodies signal the dorsal…

The hyperventilation syndrome: a neurosis or a manifestation of magnesium imbalance? (1985)
It has been proven with clinical, psychological and electromyographic tests that the hyperventilation (HV) syndrome cannot be separated from so-called genuine tetany. Tetanic patients with and without HV are characterized by a significant hypocalcemia; but a significant hypomagnesemia is exclusively found in tetanic patients with HV attacks. Possible pathogenic mechanisms are discussed which may explain…

Adrenaline, aka epinephrine, is a hormone and medication involved in regulating visceral functions (e.g., respiration)
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node,pupil dilation response, and blood…
