Respiration

Important of Respiration in living organisms.
The breakdown of C-C bonds of complex compounds through oxidation with in cell releasing
considerable amount of energy is called respiration.
 Glycolysis : The breakdown of glucose to pyruyic acid is called glycolysis. This process occurs in
the cytoplasm of cells.
 There are three major ways in which different cell handle pyruyic acid these are lactic acid
fermentation, alcoholic fermentation and aerobic respiration.
 Aerobic respiration includes krebs cycle and oxidative phosphorylation in addition to glycolysis.
 All reaction of krebs cycle are carried out in the matrix of mitochondria and ETS (oxidative
phosphorylation) carried out on inner membrance of mitochondria.
 Respiratory pathway is involved in both anabolic and catabolic processes and hence it is also
known as an amphibolic pathway rather then as a catabolic one.
 During aerobic respiration O2
is consumed and CO2
is released. The ratio of CO2
to the O2
consumed during respiration is called Respiratory Quotient (RQ)
