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.
