Question

Explain the 3 various pathways of break-down of glucose in respiration. plz give a crct answer​

Answer 1

1) = In the presence of oxygen breaking down of glucose in pyruvate. 2) = Takes place in mitochondria of a cell. 3) = End products are carbon dioxide , water. 4) = More amounts of energy released.

Answer 2

Answer:

Breaking down of glucose can occur by various pathways ;

⑴ In presence of oxygen :

- Breaking down of glucose into pyruvate takes place in Mitochondria of a cell.

- End products are CO₂ , H₂O and energy.

⑵ In insufficient presence of oxygen :

- In muscle cells, due to insufficient presence of oxygen the cells undergoes anaerobic respiration.

- End products are Lactic acid and lot amount of energy.

⑶ In absence of Oxygen :

- In absence of Oxygen, glucose breakdown into pyruvate in cytoplasm only.

- End product are Ethanol, and small amount of energy.
