Question

Which compound has the highest concentration in a cell?

• A. ${\mathrm{CO}}_2$
• B. ${\mathrm{CH}}_4$
• C. Water
• D. Glucose

Answer 1

The correct option is C

Water

Explanation for the correct options:

Cell:

• All living organisms and body tissues are made up of cells. Cells are the smallest units that can live on their own.
• Water can be found within and outside of cells. Although a mammal's body is about the same size as a human's, and contains approximately $70\%$ of water or $5\%$ water by weight.
• Out of which, $46\%$ (about $2/3$) is found inside cells, and $23\%$ (approx.$1/3$) may be found in blood plasma and other bodily fluids outside of cells.
• The cell has a higher water concentration than the surrounding medium, implying that it contains less solutes.
• A hypertonic solution is one that has this property.
• Water molecules flow from the inside to the outside of the cell through the cell membrane in this example.

Explanation for the incorrect answer:

Option (A) , when the cell of our body burns sugar, Carbon dioxide is produced.

Option (B): Methane is not one of the constituent of a living cell.

Option (D) : Sugar is stored as glucose subunits in the large branching polysaccharide glycogen, which is found in the cytoplasm of many cells, including the liver and muscle, as tiny granules.

Therefore, option (C) is correct answer.
