Question

explain the break down of glucose by various pathways

Answer 1

heya!!

Break down of glucose to provide energy is called Respiration.

These are of two types :-

*** AEROBIC RESPIRATION ***

this type of respiration takes place in the present of oxygen and takes place in mitochondria of the cell.

=> glucose + oxygen ------> Carbon dioxide + water.

*** ANEROBIC RESPIRATION ***

this type if respiration generally takes place in absence or lack of oxygen.

lack of oxygen :-

=>glucose + oxygen = lactic acid + carbon dioxide

formation of lactic acid in muscle cells leads to cramp.

Absence of oxygen :-

=>glucose + oxygen = ethanol + carbon dioxide.

=>it takes place in yeast cell.

=>known as fermentation.
