All are true about ATP except:
Correct answer: C. Contains three high-energy bonds
- A. Energy currency of the cell
- B. Contains ribose sugar
- C. Contains three high-energy bonds
- D. Contains three phosphate groups
Explanation
Option C is correct because ATP contains only two high-energy bonds, not three. These high-energy bonds are found between the first and second phosphate groups and the second and third phosphate groups. The bond linking the third phosphate group is not considered high-energy. The other options are true statements about ATP: it acts as the energy currency of the cell, it contains a ribose sugar, and it has three phosphate groups.

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.
