A
Adenine, ribose, and three sulfate groups
B
Guanine, ribose, and three phosphate groups
C
Adenine, ribose, and three phosphate groups
D
Adenine, deoxyribose, and three phosphate groups
Verified step by step guidance1
Recall the structure of ATP (adenosine triphosphate), which is a nucleotide involved in energy metabolism and nucleic acid chemistry.
Identify the three main components of ATP: a nitrogenous base, a sugar, and phosphate groups.
Recognize that the nitrogenous base in ATP is adenine, a purine base.
Understand that the sugar in ATP is ribose, a five-carbon sugar with a hydroxyl group on the 2' carbon, distinguishing it from deoxyribose which lacks this hydroxyl.
Note that ATP contains three phosphate groups attached in a chain to the 5' carbon of the ribose, which are key to its role in energy transfer.
