In ATP (adenosine triphosphate), which set correctly lists the three main structural components of the molecule?
A
Guanine, ribose, and two phosphate groups
B
Adenine, deoxyribose, and three phosphate groups
C
Adenosine, glycerol, and three fatty acid chains
D
Adenine, ribose, and three phosphate groups
Verified step by step guidance1
Step 1: Understand the structure of ATP by breaking it down into its three main components: a nitrogenous base, a sugar, and phosphate groups.
Step 2: Identify the nitrogenous base in ATP, which is adenine, a purine base commonly found in nucleotides.
Step 3: Recognize the sugar component in ATP, which is ribose, a five-carbon sugar with a hydroxyl group on the 2' carbon (distinguishing it from deoxyribose).
Step 4: Note that ATP contains three phosphate groups linked in a chain, which are key to its role in energy transfer.
Step 5: Combine these components to confirm that the three main structural parts of ATP are adenine, ribose, and three phosphate groups.
