Unifying Geochemical Scenario for the Origin of a High Cellular Potassium to Sodium Ratio in Living Cells

Potassium ion is the most common compound in all living organisms, with intercellular [K+]:[Na+] ratios greater than 1 across all domains of life. While most natural aquifers are rich in sodium, it is believed that localized potassium-rich environments were crucial for initiating prebiotic reaction networks leading to the origin of... Show more
