Minerals and Nutrients

Mg binds to phosphate group in ATP thus making a complex that catalyses phosphate transfer. 

In plants, $Mg^{2+}$ is present in chlorophyll which is a green pigment useful for photosynthesis. It absorbs sunlight.

Calcium strengthens bones and teeth in our body. It is an inorganic substance which is later converted to its organic forms when it gets combined with carbon molecule.

Nitrogen is one such element which is very important in plant growth because it is an essential part of the chlorophyll that is the site of photosynthesis.

In NH3 (ammonia), nitrogen is in the -3 oxidation state, which is its most reduced form. In CO2, carbon is in the +4 state (oxidized); in H2O, hydrogen is in the +1 state; in sulphate, sulphur is in the +6 state.

A comparison of elements present in non-living and living matter is given in the table below:

Iron is an important component of hemoglobin which is present in red blood cells. It carries oxygen from lungs to different parts of the body. Sources of iron includes sunflower seeds, nuts, beef, beans, green leafy vegetables, tofu, amla, jaggery. Iron deficiency can leads to anemia, that is low number of hemoglobin as there is insufficient iron in the body to produce enough of hemoglobin.

The phenomenon of breaking up of water into hydrogen and oxygen in the illuminated chloroplasts is called photolysis or photocatalytic splitting of water. It can be depicted as: $4H _{2} O \rightleftharpoons 4H^{+} + 4OH^{-}$
   $4OH^{-}\xrightarrow[Mn^{2} + ,Ca^{2} +, CI^{-}]{Oxygen \,\, evolving \,\, complex} 2H _{2}O + O _{2}\uparrow + 4e^- $

Greenhouse gases like carbon dioxide (CO2), water vapor, and nitrous oxide (N2O) are key elements in the atmosphere that alter the Earth's energy balance by trapping infrared radiation.

Nodulation in legumes requires several minerals, but sulphur and potassium are critical for the development of nodules and the synthesis of nitrogenase enzymes.

Blood clotting factors are needed for blood to clot (coagulation). Prothrombin is one of the clotting factors made by the liver. During normal blood coagulation, a coagulation cascade activates prothrombin by converting it into the serine protease thrombin. Thrombin then converts the soluble fibrinogen into insoluble fibrin strands. These strands are then cross-linked by factor XIII to form a blood clot. As soon as blood from a wound is exposed to the air, the platelets disintegrate and react with fibrinogen to create fibrin: a mass of tiny threads. This triggers a whole series of reactions that rely on adequate levels of calcium and vitamin K to work. Calcium is also an important part of the blood clotting process. Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. It is not present in the blood.

Green plants generally do not suffer from phosphorus deficiency because it is a vital component of nucleic acids, ATP, and phospholipids, and plants have evolved efficient uptake mechanisms. While other elements are also essential, phosphorus is frequently cited in this context regarding plant nutrition and soil availability.

The lithosphere serves as a source of minerals. The minerals supply the basic materials, required for making a variety of commodities, which man uses daily. The lithosphere is also the major source of fuels, such as coal, petroleum and a natural gas. 

As rock becomes broken down through a variety of processes, such as weathering and erosion, the particles become ground smaller and smaller. The four main bases in a soil are Nitrogen, Phosphorus, Iron and Potassium.
