Importance of phosphates to the metabolism in both plants and animals

By far the greatest portion of phosphorus is devoted to maintain and support the skeleton. In the soft tissuesphosphorus is a major component of the cellsmembranes and body fluids. But also plays an important role in the energy supply. In addition phosphorus acts as a buffer, is involved in phospholipids and fatty acids transfer, in the formation of amino acids and in makes part of DNA and RNA.

The Function Of Phosphorus In Plants And The Garden

In this article we will discuss about: Introduction to Phosphorylation 2. Definition of Phosphorylation 3. Certain organic phosphates, formed in the tissues out of anabolic chemical reaction, play a key role in the energy transactions of living organisms. The work of Embden, Meyerhof, Cori and their associates show that organic phosphates concerned with the metabolism of glucose by yeast are also intermediates in the metabolism of glycogen and glucose in muscle and other tissues.

The sugar phosphates, although not high-energy compounds, are obligatory intermediates. The reverse changes are called dephosphorylation, where phosphoric acid is dissociated from the compound. These two processes are probably the reversible reactions of the same enzyme system.

Physiological Importance of Phosphorylation: Phosphoric acid enters into the composition of cell protoplasm. Hence, phosphorylation is an essential chemical process for all cells. In addition to this it takes an essential part during absorption and metabolism of different foodstuffs.

Its effect in the different channels of metabolism are summarised below: In Relation to Carbohydrates: Absorption of carbohydrates through the intestinal mucosa and also reabsorption of glucose from renal tubules, are helped by phosphorylation.

In both the epithelia hexose phosphate is formed. This compound undergoes dephosphorylation, hexose enters the blood stream and phosphoric acid is left behind.

Formation of glycogen from glucose and breakdown of glycogen into glucose in the liver and muscles are believed to take place through the process of phosphorylation. As a matter of fact phosphorylation and dephosphorylation alternately go on in this process.

Glycogen is broken down up to lactic acid through a series of phosphorylated compounds. The phosphorylation of carbohydrate metbolites takes place in two stages: This reaction can take place only in presence of intact oxdation process and the energy-yielding oxidation mechanism is coupled with energy-harnessing phosphorylation mechanism.

Uncoupling agents like 2, 4-dinitrophenol inhibit phosphorylation but not oxidation. They elevate the oxygen consumption rate. The second stage in phosphorylation process is transfer of phosphate group from ATP to other intermediates.

Oxidative phosphorylation takes place in the cristae of the mitochondria Fig. In relation to Fats: During absorption of fats, neutral fats and phospholipids are synthesised in the absorbing epithelium.of pesticide metabolism in plants and microorganisms and examines the importance of these biochemical pathways for pesticide development and environmental stewardship.

have been characterized in animals, plants, bacteria, and fil-amentous fungi. In plants. Phosphorus is widely distributed in both plant and animal foods. Diet rich in protein and calcium provide sufficient phosphorus. Eggs, milk, meat, poultry, fish and flour are excellent sources of phosphorus.

Elements such as iron, copper, cobalt, manganese, iodine, selenium, etc., are required by plants and animals in very small quantities and are termed trace elements. The importance of the inorganic salts will be understood from the fact that salt starvation causes death much earlier than food starvation.

Importance of phosphates to the metabolism in both plants and animals

The animals and plants are important to the rainforest as they contribute to the way it works, without them there would be no rainforest ecosystem. Many of the plants and animals in the rainforest are endemic to it, which means that they are unique to their area. Both plants and animals have evolved mechanisms that help to anchor them to the substratum in flowing water (e.g., the holdfast of kelp or the byssus threads of mussels).

If anchorage can be assured, there are many advantages to living in this environment. Introduction to Phosphorylation: Certain organic phosphates, formed in the tissues out of anabolic chemical reaction, play a key role in the energy transactions of living organisms.
