Given nucleotide is most energetic at point:
Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
The nucleotide is most energetic at point D because it is in the form of ATP, which contains three phosphate groups. The bonds between these phosphate groups store significant energy, which is released during hydrolysis. Option A is incorrect as a nucleoside has no phosphate groups and thus lacks stored energy. Option B is incorrect because AMP, with one phosphate group, is less energetic than ATP. Option C is incorrect as ADP, with two phosphate groups, has less stored energy compared to ATP.

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.
