Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg2+ ion. It is an essential mineral nutrient (i.e., element) for life and is present in every cell type in every organism. For example, ATP (adenosine triphosphate), the main source of energy in cells, must bind to a magnesium ion in order to be biologically active. What is called ATP is often actually Mg-ATP. As such, magnesium plays a role in the stability of all polyphosphate compounds in the cells, including those associated with the synthesis of DNA and RNA.
Over 300 enzymes require the presence of magnesium ions for their catalytic action, including all enzymes utilizing or synthesizing ATP, or those that use other nucleotides to synthesize DNA and RNA.
In plants, magnesium is necessary for synthesis of chlorophyll and photosynthesis

❤. signicicane of mg2+
mg2+ ions are concentrated in animal cells.
Enzymes like "phosphohydrolases'and 'phospho transferases'contains Mg2+ ions.
These enzymes participate in ATP reactions and release energy in the process Mg2+ forms a complex witg ATP
Mg2+is a constitute of chlorophyll, the green component of plants.
