transport phenomena in biological system

Burning the petroleum products to run automotive transport vehicles is the main cause of air pollution. The main pollutants like SO 2 , CO, CO 2 are main gases being released into air due to transport vehicles. But, the extent of pollution due to transport vehicles is ..

Electron transport chain refers to the light driven reactions of photosynthesis. They were first formulated in 1939 by Robert Hill. The two photosystems are connected in series with each other by the components of electron transport system. The reaction centres become ..

Electron Transport System - The metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system. Electron Transport System (ETS) in Mitochondrion The electron transport ..

Cyclic Electron Transport System - Cylic reaction transport occurs only occasionally when synthesis of carbohydrate is curtailed due to limited supply of CO 2 and NADPH 2 starts accumulating. At this time, there would be no need for additional NADPH 2 . Moreover, the c..

Circulatory System - The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particu..

As mentioned earlier, the transport in higher plants is with the help of the vascular system. Thus, these plants are also called the vascular plan..

Materials to be transported include digested food, respiratory gases, hormones, excretory products, etc. The digested food includes sugars like glucose, amino acids, fatty acids and their derivatives. Blood which is the vascular tissue in man is over 90% water. Thus, only the water-solubl..

The food is digested into the simplest of the forms in t he digestive system. Blood carries the digested food or the nutrients absorbed from the intestine to the liver and then to other parts of the body. The food transported includes glucose, fatty acids, amino acids, glycero..

The light energy of specific wavelengths is absorbed by chlorophylls and accessory pigments of PS-II. These pigments transfer their absorbed energy to PS-II reaction centre - P 6 8 0 (chlo 680). This centre become photo excited and exudes an electron with a gain of energy (23 K Cal/mol..
