Explain about RESPITATION ?..

Answer / subodh shukla

The process of oxidation and decomposition of organic compounds particularly glucose, the simple carbohydrate, in the living cells with the release of energy is known as Respiralian

During this process, the potential energy stored in organic compounds in the living cells is released as active or kinetic. This process is catalysed by certain enzymes and released energy is used by the protoplasm for its activities such as manufacture of foods movements, growth, reproduction, etc.

The process of respiration involves

(1)Consumption of atmospheric oxygen.

(2)Oxidation and decomposition of part of stored food.

(3)Liberation of carbon dioxide and also small quantity of water.

(4)Release of energy by breakdown of organic food.

Chemical reactions involved in the process of respiration are

C6H12O6 + 6O2  6CO2 + 6H2O + energy
(Sugar +OxygenCarbon dioxide + Water +energy)

It means 6 molecules of carbon dioxide and water are formed by oxidation of only one molecule of sugar along with six molecules of oxygen.

Growing regions of plants respire more actively than the adult regions. Growing regions are stem and root tips, germinating seeds, vegetative buds etc..
