what are biological significance of inorganic metals as Na,Cl,Fe,I,Zn,Co?

Question

in the answer i will like to get significance in plants and animals with the structure of compound in which the metal is present and its ionic state in he compound and its functions as well

Answer 1

Sodium, Iron, Zinc and Cobalt are metals. Chlorine and Iodine are non-metals (in the halogen family). A complete list of their occurances would be extremely long.

Sodium chloride (NaCl) is commonly found in the ionic form in the blood and extracellular fluids of mammals.

Potassium (K) is commonly found as an ion inside animal cells.

Iron (Fe) is found in hemoglobin in red blood cells and myoglobin in muscle cells where it is required for oxygen transportation. The iron is complexed with protein.

Iodine (I) is part of thyroxin, a hormone produced by the thyroid gland that controls the body's rate of physical and mental development. The iodine is covalently bonded.

Zinc is found in over 200 different enzymes in both plants and animals. It is often found in ionic as well as complex form.

Cobalt is found in many compounds including Vitamin B-12.

Answer 2

Na and Cl are required for osmotic pressure of the cells. Na is also required for action potentials in nerves which helps carry the stimulus.
Fe and Co are metals bound by proteins. Several of those are important in redox reactions and electron transport.
Zn is another metal often bound by proteins. One of the best known examples is Zn-finger proteins which bind DNA.

Answer 3

all the metals are of immense importance....Na and Cl are present in the brain......Cl is a major component of the viscous fluid in the brain the name of which i have forgotten.....NaCl is an essential salt........Fe helps in blood transport and is the major content of haemoglobin
