Question

Explain the process of breakdown of C6 h12 o6 in a Cell day in the absence of O2 and in the presence of O2

Answer 1

HELLO !

BREAKDOWN IN PRESENCE OF OXYGEN = Glucose (6 carbon molecule) breaks into pyruvate(3 carbon molecule) which further breaks into carbon dioxide and water .

BREAKDOWN IN ABSENCE OF OXYGEN = Glucose breaks into pyruvate 
which further breaks into ethanol  and carbon dioxide releasing energy .

BREAKDOWN IN LACK OF OXYGEN = Glucose breaks into pyruvate further breaking into lactic acid and energy .
