Question

Explain the ways in which glucose is broken dowen in absence of oxygen

Answer 1

HEY MATE ^^

Glucose is oxidized in the following ways:

a. In cytoplasm, glucose is oxidized to pyruvate and release energy

b. In muscles of humans i.e. under anaerobic conditions pyruvate breaks down to lactic acid and release energy.

c. In yeast i.e. during fermentation process pyruvate converts to ethanol, carbon dioxide along with it releases a certain amount of energy

Answer 2

HOPE IT WILL BE USEFUL

ABSENCE OF OXYGEN:

YEAST FORMATION

GLUCOSE====== PYRUVATE====== 2ETHANOL+2CO2+2ATP

LACK OF OXYGEN

GLUCOSE====== PYRUVATE====== 2LACTIC ACID+2ATP
