Transmission of nerve impulses, release of insulin from pancreas. Cofactor for many enzymes. Bone formation. 1 of 14 Sodium? Na+. Nerve impulses. Muscle contraction. Regulating fluid balance in body. 2 of 14 Potassium? K+. Nerve impulses. Muscle contraction. Regulating fluid balance. Activates essential enzyme for photosynthesis in plants. 3 of 14 Hydrogen? H+. Affects pH of ions, more H+ ions is more acidic, also involved in photosynthesis reaction that takes place in the thylakoid membranes. 4 of 14 Ammonium? NH4+. Absorbed by plants from soil, important source of nitrogen for e.g amino acids, nucleic acids. 5 of 14 Nitrate? NO3-. Absorbed by plants from soil. Important source of nitrogen. 6 of 14 Hydrogen Carbonate? HCO3-. Acts as a buffer, maintains pH of blood. 7 of 14 Chloride? Cl-. Involved in Chloride shift that helps maintain pH of blood during gas exchange. Acts as a cofactor for enzyme amylase. Some nerve impulses. 8 of 14 Phosphate? PO43-. Photosynthesis and respiration reactions. Needed for synthesis of biological reactions eg nucleotides, phospholipids, calcium phosphate. 9 of 14 Hydroxide? OH-. Affects the pH of substances. More OH- creates more Alkali. 10 of 14 Cation? Ion with a positive charge. 11 of 14 Anion? Ion with a negative charge. 12 of 14 Inorganic Ion? Contains NO carbon. Important in biological processess. 13 of 14 Ion? Atom with an electric charge. 14 of 14
