Why do we respire?
Ans:
We respire to use the oxygen, to oxidise our food and release energy. This is similar like burning but a slower process. it also needs respiratory enzymes .Respiration is a slower process than burning and energy released can be stored for later use.
C6 H12 O6+ O2------------------> H2O+ CO2+energy
Why we should eat regularly?
Ans:
The food has stored energy which is released during respiration, thus we should eat regularly.
What happens to the air we breathe in?
Ans:
The air we breathe in transported to every parts of body and ultimately it is transported to each cell, in the cells, oxygen in the air helps in the breakdown of food, this process of breakdown of food in the cell with the release of energy is called cellular respiration.
Differentiate between aerobic and anaerobic respiration.
Ans:Aerobic respiration
An aerobic respiration takes place using oxygen, inhaled in breathing.
In aerobic respiration , breakdown of glucose results in production of Carbon Dioxide, Water and Energy
An aerobic respiration uses respiratory organs such as lungs or gills.
Anaerobic respiration
Whereas an anaerobic respiration requires no oxygen.
In anaerobic respiration, the breakdown of glucose first results in Lactic Acid and energy then lactic acid break down into carbon dioxide and water.
anaerobic respiration take place at cellular or muscular level
