Inorganic Ions

HideShow resource information
Calcium?
Ca2+. 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.
