These ions are concentrated more in intracelluar then in extracellular fluids in animal bodies

Activation of phosphate transfer enzyme takes place in their presencde

They are involved in carbohydrate metablism

All are correct statement

${\text{M}}{{\text{g}}^{{\text{2 + }}}}$ ion form a complex with ATP

${\text{C}}{{\text{a}}^{{\text{2 + }}}}$ on are important in blood clotting

${\text{C}}{{\text{a}}^{{\text{2 + }}}}$ ion are not important in maintaining the regular beating of the heart.

${\text{M}}{{\text{g}}^{{\text{2 + }}}}$ ion are important in the green parts of plants.

$Mg^{2+}$ ion forms a complex with $ATP$

$Ca^{2+}$ ions are important in blood clothing.

$Ca^{2+}$ ions are not important in maintaining the regular beating of the hear

$Mg^{2+}$ ions are important in the green parts of plants

The halides of beryllium are electron deficient and are polymeric with halogen bridges.

$BeF _2$ is very soluble in water owing to high solvation energy of Be but fluorides of other alkaline earth metals are almost insoluble.

CaO, SrO and BaO react exothermically with water forming soluble hydroxides.

The bicarbonates of alkaline earth metals are only stable in solutions.

$Mg^{2+}$ ions are necessary for the activation of phosphate transfer enzymes.

Mg is present in chlorophyll of green plants.

Mg is present in chlorophyll used in photosynthesis in green plants.
