1) Greatest reservoirs of phosphate are the insoluble ferric and calcium phosphates in rocks (rock phosphate) in combination with calcium, iron and aluminium. Slow process of weathering releases phosphates to the soil. 2) Phosphates are also added t..

Phosphate esters play a vital role in the life processes. The most important of these biomolecules are DNA, RNA, adenosine mono-, di- and tri- phosphates (AMP, ADP and ATP). Hydrolysis of P-O-P link in ADP releases energy, which can be put to useful wor..

i) Considerable amount of phosphorus from the soil rock is washed into the sea by rains and floods (an estimated amount of 2 million tonnes of phosphotic rock is lost to sea) where sea weeds take up phosphorus and is then passed onto fishes and sea birds. ii) Terrestrial plants absorb phosphorus as..

Pentose Phosphate Pathway - In some microorganisms, biological oxidation of glucose follows a different pathway. It is known as pentose phosphate pathway or hexose mono phosphate shunt or direct oxidation of glucose. Pentose Phosphate Pathway In pentose pathw..

Some bacteria like Aspergillus awamori have the capacity to solubalise the phosphates fixed in soil. It must be recalled here that most of applied phosphorus is fixed in soil, and a small part of it is available to plants every year as labile phosphorous. When such bacteria are grown in l..

Apparatus required: Sections of a chlorophyll-free leaf, platinum chloride or picric acid or sodium cobaltnitrate, distilled water, glass slides, cover slips and microsc..
