Presentation Transcript

Respiration : 

Respiration Respiration is catabolic and anabolic process in which complex substance are broken into simpler form and ATP energy is released . Respiration is vital process which occur in all living cells of the plant but most actively respiring part are growing region like floral, vegetative buds, germinating seedling stem and root apices. During normal condition the process involve of oxygen and conversion of potential energy into kinetic energy. The overall respiration process may be represented as. C6H12O6 + 6O2 6CO2+ 6H2O + 686 KCAL

Significance of Respiration : 

Significance of Respiration It release energy in form of ATP. Oxidation of food. Complex compound to simple compound. Exothermic.( Release of heat) Release of hydrogen. Energy is conserved. Enzymatically controlled. At low temperature. In living cell.

Types of Respiration : 

Types of Respiration Aerobic Respiration It takes place in the presence of O2 and stored food ( Respiratory substrate ) get completely oxidized into CO2 and H2O. C6H12O6+6O2 6CO2 + 6H2O + 686 Kcal. Anaerobic Respiration It takes place in the absence of O2 or when conc. Less than 1% . The store food incompletely oxidized and instead of CO2 and H2O. C6H12O6 2C2H5OH + 2CO2 + 56 Kcal.

Slide 4: 

Mechanism of Respiration Respiratory substrate may be carbohydrates , fat , and in certain condition protein. Complex carbohydrates hydrolysis by Hexose’s sugar Fats Fatty acid. Protein are utilized only when carbohydrates or fats not available. The first phase of respiration during which carbohydrates were used up had been termed by Blackman as the floating respiration. The second phase of respiration in which protoplasmic protein were used up had been termed by Blackman as the protoplasmic respiration. The most common respiratory substrate is Glucose. enzyme hydrolysis Lipase

Slide 5: 


Slide 6: 

Cellular Respiration Includes pathways that require oxygen Glucose is oxidized and O2 is reduced Glucose breakdown is therefore an oxidation-reduction reaction Breakdown of one glucose results in 36 to 38 ATP molecules What are the Stages of Cellular Respiration? Glycolysis The Krebs Cycle The Electron Transport Chain

Slide 7: 

Where Does Cellular Respiration Take Place? It actually takes place in two parts of cell Glycolysis occur in cytoplasm Krebs’s cycle takes place in the mitochondria
