THE RESPIRATORY SYSTEM

Respiration is vital process in all living organisms.It gones non-stop through out life.It is process in which the raw materials used ,the end-product used and the amount of energy liberated.So it is process in which the raw material used or the chemical process of releasing energy by breaking down giucose for carrying the life process.There is five points to be rembeber this part of respiration yielding energy occurs inside the living cells and hence it is better known as cellular or tissue respiration.
2>The breakdown of glucose to carbon dioxide and water does not occur in a single steps but in a series of chemical steps.some of the steps occur in cytoplasm and inside the mitochondria.
3>The breakdown of process is envolve the enzyme citrase kinase.
4>ATP release from the adenosine triphosphates first discovered by KARL LOHAMM IN 1929.We get energy in the form heat  in which adp first converted into ATP .It is also called as currency of energy in side the cell. One mole of glucose on complete oxidations yields 28 molecules of ATP.
5>The essensials steps of cellular respirations are same in plants and animals.
WHY WE NEED ENERGY-We need energy for a vast variety of activities in them.Some of these are:
1>Synthesis of protein from aminoacids.
2>productions of enzymes.
3>contractions of muscles for movements.
4>conductions of electricals impulse in a nerve cell.
5>By cell divisions formations of new cells.
6>For keeping the body warm i,e warm-bloded animals e,g birds and mammals.
