Which of the following is most similar in structure to ATP?
A) a pentose sugar
B) a DNA nucleotide
C) an RNA nucleotide
D) an amino acid with three phosphate groups attached
E) a phospholipid

Question

Quizplus · Accepted Answer

ATP is a nucleotide, composed of a nitrogenous base (adenine), a sugar (ribose), and three phosphate groups. Similarly, an RNA nucleotide also contains a nitrogenous base (adenine, guanine, cytosine or uracil), a ribose sugar, and a phosphate group. Pentose sugar, amino acids, and phospholipids do not have a similar structure to ATP. While DNA nucleotide also contains a nitrogenous base (adenine, guanine, cytosine or thymine), a sugar (deoxyribose), and a phosphate group, it lacks the third phosphate group, which is essential for ATP's energy transfer function.
