The circulating red blood cell is metabolically active but is only able to live for 120 days. During this short time, some significant enzymes are gradually broken down and this may contribute to the death of the cell. Explain why the red blood cell is not able to replace important enzymes that have been broken down.

They lack nucleus and other organelles important for the synthesis of the enzyme.

Explanation:

The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.

The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.

As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
