Biology inorganic ions

Calcium ions (Ca²⁺)

Involved in muscle contraction and nerve impulse transmission

Sodium ions (Na⁺)

Involved in co-transport, reabsorption of water in the kidney, regulating water potential and nerves impulse transmission.

Potassium ions (K⁺)

Involved in stomatal opening and nerve impulse transmission.

Hydrogen ions (H⁺)

Involved in chemiosmosis, regulating pH and translocation.

Ammonium ions (NH₄⁺)

Involved in nitrogen cycle, where by bacteria convert ammonium ions into nitrate ions.

Nitrate (NO₃⁻)

Mineral ion absorbed by plants to provide a source of nitrogen to make amino acids.

Hydrogencarbonate (HCO₃⁻)

Involved in the transport of carbon dioxide in the blood.

Chloride (Cl⁻)

Involved in the transport of carbon dioxide in the blood as they are part of the chloride shift to balance positive charges.

Phosphate (PO₄³⁻)

Involved in the formation of phospholipids for cell membranes, nucleic acid and ATP formation.

Hydroxide (OH⁻)

Involved in the catalysis of reactions and regulating pH.
