Correct Answer: Option n
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.
