Biology 9 Chapter 11 - Test 1


1. A molecule of glucose on complete oxidation releases 9000 calories energy.


2. The chemical energy of glucose, protein and fatty acids on degradation is trapped into small packets of energy in the form of ATP molecules.


3. A molecule of ATP on its breakdown releases only 1000 calories of energy.


4. The oxidation of absorbed food material in order to obtain energy is called photosynthesis.


5. In anaerobic respiration considerably less amount of energy is produced as compared with other type of respiration.


6. The type of respiration in which oxygen is used is called anaerobic respiration.


7. There are four stages of acrobic respiration.


8. ATP is an abbreviation of adenosine triphosphate.


9. The two terminal bonds between the phosphate group contain very low amount of energy.


10. When ATP is converted into ADP, 7,300 calories energy released.


11. Many useful bacteria and yeast are anaerobic.


12. Plants have a well developed system for exchange of gases.


13. The aquatic parts of plants obtain oxygen for their respiration by diffusion.


14. The respiration in plants continues day and night.


15. In amphibia and fishes the gaseous exchange occurs only through skin.


16. The gills are very effective gaseous exchange in terestrial animals.


17. In human respiratory system the upper part of the air tube is called larynx.
