Question

Describe the different pricesses of release of energy from glucose in living organism?

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.
