Answer 2

Answer:

Glucose

Explanation:

Every cell of the body needs glucose for carrying out the metabolic processes taking place inside it. As the cell is inside blood collection tube,there will be no synthesis of erythrocytes in the tube.

The components like iron, calcium and vitamin B 12 is required for the synthesis of erythrocytes so there is no need of such components.

The cell will only require glucose to stay alive in the blood collection tube.
