Water makes up approximately what percentage of fat cells by mass?

Ten percent
Five percent
Twenty percent
Fifteen percent

The correct answer is: Five percent

Fat cells, also known as adipocytes, primarily store energy in the form of fat. However, they also contain a proportion of water. The correct answer indicates that water accounts for about five percent of the mass of fat cells. This relatively low percentage reflects the primary role of adipocytes in fat storage, where the lipid (fat) content significantly outweighs the water content. While there is a small amount of water involved in metabolic processes within these cells, its overall presence remains minor compared to the lipid stores. Water is essential for various physiological functions, but in the context of adipose tissue, the overall structure is predominantly composed of stored fats rather than aqueous solutions.
