The percentage of water in a bacterial cell is about:
Correct answer: D. 70%
- A. 15%
- B. 18%
- C. 50%
- D. 70%
Explanation
The correct answer is 70%. Bacterial cells, like most living cells, contain a high percentage of water. This high water content is essential for various cellular processes such as metabolism, nutrient transport, and temperature regulation. Water acts as a solvent for biochemical reactions and helps maintain cell turgor pressure, which is necessary for maintaining cell shape and structure. Other options, such as 15%, 18%, and 50%, underestimate the actual water content and do not account for the vital roles that water plays in bacterial cell function.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
