Answer:
The cations of Na and K are present in red blood cells. The concentration gradient (the ratio K
+
:Na
+
) in mammals (humans, rabbits, rats and horses) is 7:1. This ratio in cats and dogs is 1:15. Work has to be done to establish this concentration gradient. This is done by various mechanisms involving sodium pump and potassium pump. These gradients control the development and functioning of nerve cells.
Chlorophyll contains Mg
2+
ions. Chlorophyll absorbs sunlight and carries the process of photosynthesis.
Ca
+2
ions are present as phosphates in bones of humans and animals. They play an important role in muscle contraction. Their deficiency causes malnutrition in children.
Both Ca
2+
and Mg
2+
ions catalyze the formation of pyrophosphate linkages which control the various biological systems.

Answer:
The main role of this ion in the body is to regulate the functions of enzymes which in turn are responsible for various chemical reactions. Magnesium as an enzyme co-factor plays an important role in the breakage of glucose and fat molecules, in the production of enzymes, proteins and regulation of cholesterol.
