Question 1.


(a) Respiration

(b) Combustion

(c) ATP


(a) Respiration — Respiration is a catabolic process of releasing energy from glucose for carrying out life processes.

(b) Combustion — Combustion or burning is defined as a physio-chemical process in which energy is liberated in the form of heat and light.

(c) ATP — ATP is defined as energy currency of the cell as it acts as the immediate source of energy for different life processes.

Question 2.


(a) Two raw materials of respiration.

(b) Two end products of aerobic respiration.

(c) Two microbes which normally respire anaerobically


(a) Glucose and Oxygen

(b) Carbon dioxide and water

(c) Bacteria and Fungi

Question 3.

Write the full forms of ATP and ADP.


ATP: Adenosine triphosphate

ADP: Adenosine diphosphate

Question 4.

What happens to the energy liberated in respiration?


The energy liberated in respiration is stored in the form of ATP inside the cells. Some part of it is lost as heat to the surroundings.

Question 5.

How is tilling of the soil useful for the crops growing in it?


Tilling makes the soil porous and airy. The underground parts of the plants get sufficient amount of oxygen for respiration. In this way, tilling helps the crops to grow faster.

Question 6.

Why is it usually difficult to demonstrate respiration in green plants?


During day time, both photosynthesis and respiration takes place in green plants. Evolution of COis an indicator to demonstrate respiration in living organisms. CO2 produced during respiration in plants gets utilized during photosynthesis and thus, there is no evolution of CO2. Therefore, it is difficult to demonstrate respiration in green plants as there is no evolution of CO2 during day time.

Question 7.

Can cell respiration occur in any organism at a temperature of about 65C? Give reason.


Cell respiration cannot occur in any organism at a temperature of about 65C because the enzymes involved in respiration become inactivated at high temperatures.
