(a) Write the chemical equation for each of the following processes:
(i) aerobic respiration
(ii) anaerobic respiration in plants
(iii) anaerobic respiration in animals.

(b) State four functions which the liver of a patient suffering from cancer of the liver will not be able to perform.

(c) Make a diagram 8 -10 cm long of a flame cell and label fully. 

(d) Name one appropriate hormone each responsible for the following conditions in plants:
(i) ripening of fruits
(ii) breaking dormancy in seeds
(iii) weed control
(iv) leaf fall.

Explanation

(a) Chemical Equations for processes:
(i) Aerobic respiration C(_6)H(_1)(_2)O(_6) + 6O(_6)→ 6CO(_2) + 6H(_2)0 + 38ATP Energy/690k cal.
(ii) Anaerobic respiration in plants C(_6)H(_1)(_2)O(_6) –> 2C(_2)H(_5)OH + 2CO(_2) + 2ATP/Energy/50 k cal. 
(iii) Anaerobic respiration in animals C(_6)H(_1)(_2)O(_6_) → 2CH(_3)CH(OH)COOH + 2ATP/Energy/150 k cal. C(_6)H(_1)(_2)O(_6) → 2C(_3)H(_6)O(_3) + 2ATP/Energy/150 k cal.

(b) A cancerous liver will not be able to: –

  1. regulate blood sugar
  2. carry out detoxication/deamination/regulation of blood proteins
  3. produce bile
  4. form red blood cells
  5. produce heat
  6. store vitamins
  7. regulate lipids
  8. manufacture protein
  9. store iron
  10. reserve blood.

Labels: Cell lumen, nucleus, basal granule, flagellum/cilium, excretory duct, excretory tubule, cytoplasmic process, vacuole
