1. Chapter -5 Life processes
Respiration in different organism

2. Respiration
REPIRATION-The process in which food molecules oxidized and release energy
is called respiration. there are two types of respiration found in living being.
(a) Aerobic respiration - The process in which food molecules oxidize in the presence
of oxygen is called aerobic respiration
C6H12O6 + O2 → CO2 + H2O + 686 kcal energy
(b) Anaerobic respiration - When food molecules oxidized in the absence of oxygen
is called anaerobic respiration
C6H12O6 → C2H5OH + CO2 + 56 K. Cal energy

3. Differences between aerobic and anaerobic respiration
Aerobic Anaerobic
1. It is takes place in the presence of
oxygen
Its takes place in the absence of oxygen
2. Food molecules are completely
oxidised
Food molecules are not completely
oxidised
3. The end product of aerobic respiration
of CO2 and H2O
End product of anaerobic respiration are
C2H5OH and CO2
4. Large amount of energy is released Less amount of energy released
5. Its take place in the matrix of
Mitochondria
Take place in the cytoplasm of cell
6. Generally, it is found in higher organism Generally, it is found in lower organism

4. Respiration in plants
Through the
leaves
Through the
lenticels
Through the
roots

5. Respiration in different organisms
1. Respiration in unicellular organism (amoeba)
In the unicellular organism, Body cell is direct contact to the surrounding solution.
Concentration of O2 is higher outside compare than cell. therefore O2 move from
outside to inside. And Concentration of CO2 is higher in the cell compare than
surrounding so CO2 move from inside to outside by the process of diffusion.

6. 2. Cutaneous respiration (Annelida) - In annelids and some amphibians’ gases
exchange occur through the skin. Oxygen of atmosphere first dissolve in the mucus
layer which is present on the body surface. Dissolve oxygen enter in the body cells
through diffusion process then it is entering in the blood and transport to every cell
of the body. And carbon dioxide produced during respiration is carried back by the
same path.

7. 3.Tracheal Respiration: - Insect have spiracles on lateral side of the
body which allow air to enter the tracheal tube.. Through the tracheal tube
oxygen inter in the body cell. At the same time, carbon dioxide produced
as a waste product of cellular respiration diffuses out of the cell and
eventually out of the body through the tracheal system.

8. 4. Respiration through gills - In the aquatic animals, respiration process
occurs through the gills when water current passes from mouth to gills
then gaseous exchange take place in the gill slides. Concentration of
dissolved oxygen in water is less compared then atmosphere therefore, the
rate of breathing in aquatic animals is much faster than Terrestrial animals
