hey...mate...

here is ur answer..✔

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.

heya !!!

□The first step is break down of a 6 carbon molecule of glucose into a 3 molecule of pyruvate . This process takes place in cytoplasm of cell .

□ Further oxidation of pyruvate depends on the absence or presence of oxygen .


■ ABSENCE OF OXYGEN

》》In yeast , pyruvate is converted into ethanol and CO2 in the absence of O2 .

■LACK OF OXYGEN

》》In our skeleton muscles , pyruvate is converted into lactic acid , when there is deficiency / lack of oxygen .


■PRESENCE OF OXYGEN

》》The aerobic respiration of pyruvate occurs in the MITOCHONDRIA , the 3 carbon pyruvate molecule gives rise to CO2 and H20 .

hope it helps u dear ^_^
