Question

explain the broken down of glucose by various process​

Answer 1

Explanation:

Breaking down of glucose can occur by various pathways ;

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.

I hope this is help you...

Answer 2

glucose( 6- carbon molecule ) is first broken down into pyruvate ( 3- carbon molecule )

then in the presence of oxygen or absence of oxygen or in lack of oxygen it is further broken down to produce oxygen + co2 + energy or alcohol+ energy or lactic acid + energy ... the process of break down of glucose to produce energy is called respiration ... it is exothermic process
