heya !!!
◇The first step in breakdown of a 6 carbon molecule of glucose into a 3 carbon molecule of pyruvate.
◇This process takes place in CYTOPLASM OF THE CELL.
Further oxidation of pyruvate depends on the absence or presence of oxygen as follows :
■ABSENCE OF OXYGEN
》》In yeast , pyruvate is converted into ethanol and CO2 in the absence of oxygen.
■LACK OF OXYGEN
》》In our skeletal muscle , Pyruvate is converted into lactic acid, when there is deficiency / lack of oxygen.
■PRESENCE OF OXYGEN
》》The aerobic oxidation of pyruvate occurs in the MITOCHONDRIA, the 3 carbon pyruvate molecule gives rise to CO2 and water.
hope it helps u dear ^_^
