Question

breakdown glucose by various Pathways​

Answer 1

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.

✌✌Hey, mate here is your answer⤵

_________________________

● Break down of glucose by various pathways :-

________________________

● Absence of oxygen :-

________________________

1) = In the absence of oxygen glucose break down into pyruvate.

2) = In occurs in cytoplasm only.

3) = End products are ethanol.

4) = And also small amount of energy released.
_______________________

Presence of oxygen :-
_______________________

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.
_______________________

Lack of oxygen :-
_______________________

1) = Due to lack of oxygen in our muscle and muscle cells goes anaerobic respiration.

2) = End products are Lactic acid.

3) = And small amount of energy is released.
