Question

Difference between following
•Respiration and combustion
•Respiration and breathing
•Respiration and photosynthesis​

Answer 1

Explanation:

Respiration and Combustion :-

*Respiration :-

1)Breaking down of food .

2)Energy is liberated in the form of heat .

3)It takes place always within the body of a living organism .

4)The ignition temperature of the substance is not required to be transferred .

*Combustion :-

1)No breaking down of food .

2)Energy is liberated in the form of heat and light .

3)It is not associated with the body of a living organism always .

4)The ignition temperature of the substance is required

•Respiration and breathing :-

*Respiration :-

1)Breaking down of food .

2)Release of energy .

3)Formation of ATP.

*Breathing :-

1)No breaking down of food .

2)No release of energy .

3)No ATP formed .

•Respiration and Photosynthesis :-

*Respiration :-

1)Breaking down of food .( catabolism).

2)May be in presence of oxygen or in its absence.

3)Sun Light is not required

4)Chlorophyll is not required .

•C6H12O6 →CO2 + H2O + Energy .

•Photosynthesis :-

1)Preparation of food (anabolism ).

2)Oxygen required .

3)Sun light required .

4)Chlorophyll required

CO2 + H2O →C6H12O6 + O2 + H2O ↑

Answer 2

Hello!

a) Respiration: it occurs in living cells .there is no flame or light produced

b) combustion: it occurs in non-living and dead cells .this process is usuallu accomplained with flame and light

2)

a) respiration: it is both a physical and physiological process .it liberates energy

b) breathing : It is a physical process .Breathing donot liberate energy.
