In the context of bioenergetics, which set correctly describes the three main structural parts of an ATP molecule?
A
Adenine, ribose, and three phosphate groups
B
Guanine, deoxyribose, and two phosphate groups
C
Adenine, glycerol, and three phosphate groups
D
Adenine, ribose, and a fatty acid tail
Verified step by step guidance1
Recall the basic structure of ATP (adenosine triphosphate), which is a nucleotide composed of three main parts.
Identify the nitrogenous base in ATP, which is adenine, a purine base important for energy transfer.
Recognize the sugar component in ATP, which is ribose, a five-carbon sugar that connects the base to the phosphate groups.
Understand that ATP contains three phosphate groups linked in a chain, which are key to its role in energy storage and transfer.
Compare the options given and confirm that the correct set includes adenine (base), ribose (sugar), and three phosphate groups, matching the known structure of ATP.
