Question

Explain the three pathways of breakdown in living organism

Answer 1

Answer:

the three pathway are anaerobic(yeast), aerobic and anaerobic (humans).

Explanation:

anaerobic respiration :-

• takes place in absence of oxygen
• partial breakdown of food
• end products are ethyl alcohol, CO2 or lactic acid
• example - yeast,bacteria and some parasite

aerobic respiration :-

• takes place in presence of oxygen
• complete breakdown of food occurs
• end products are CO2 AND H2O

anaerobic respiration ( humans):-

• in absence of oxygen, in our muscles, pyruvate is converted into lactic acid
