Final answer:
Sodium fluoride preserves the glucose molecule intact for 3 days. Glucose's structural integrity is maintained by a transformation to a cyclic form with hydrogen bonds. Additionally, various cells have differing GO phase lengths due to their unique functions and factors influencing their durability.
Step-by-step explanation:
Sodium fluoride helps to preserve the glucose molecule intact, specifically for 3 days.
Cells use glucose to make polysaccharides like cellulose. When dissolved in water, glucose becomes cyclic and undergoes intra-molecular bonding, which contributes to maintaining its structural integrity. Likewise, cellulose consists of glucose units bound together with hydrogen bonds that provide strength and insolubility in water, preventing dissolution by the forces of water molecules.
The longevity of cells in different tissues varies significantly. For example, the GO phase duration for muscle and nerve cells is their lifetime, while it is much shorter for other cells like leukocytes and epidermal cells. This variance in longevity can be attributed to internal and external factors, as well as the specific functions of each cell type.
