Question

Write three pathways for breakdown of glucose

Answer 1

hey

here is yr answer

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.

Answer 2

Answer:

OF  Write three pathways of breakdown of glucose.

Explanation:

At first, glucose is broken down into three carbon molecule called pyruvate. This process happens in the cytoplasm of cells of all organisms. On the basis of presence or absence of oxygen, it is two types- Aerobic respiration and Anaerobic respiration Aerobic Respiration: This type of respiration happens in the presence of oxygen. In this respiration, glucose is complete oxidized into carbon dioxide and water. Energy is also released at the end of this process. Anaerobic Respiration: This process takes place in the absence of oxygen. In this case, pyruvic acid either converted into ethyl alcohol or lactic acid. Ethyl alcohol is usually formed in case of anaerobic respiration in microbes, like yeast or bacteria. Lactic acid is formed in some microbes as well as in the muscle cells.
