oxygen function in living systems

Metals in the Living System - Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which c..

State of the system implies the conditions of its existence. In order to understand it, let H 2 O be considered as a chemical system. H 2 O can exist in three physical states; ice, water and steam depending upon the conditions of tem..

The functions performed by the circulatory system in all animals are 1) Transport of nutrients like glucose, amino acids, vitamins, minerals 2) Transport of oxygen from the organs of respiration to the body cells. 3) Transport of carbon dioxide from the body ..

The functional group is an atom, or a group of atoms which can replace one or more hydrogen/s in a hydrocarbon. This group when present in organic compounds defines the characteristic physical and chemical properties of that particular family of organic compounds. Thus a functi..

For respiration - All air breathing animals and plants use oxygen present in air by the process of respiration. This is known as aerobic respiration. During respiration, food is burnt in living cells by using oxygen to release energy for all metabolic activities. Witho..

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source o..
