Multiple Choice
Which of the following are the components of a molecule of ATP?
A
Adenine, deoxyribose, and two phosphate groups
B
Adenine, ribose, and three phosphate groups
C
Guanine, ribose, and three phosphate groups
D
Cytosine, ribose, and two phosphate groups
Verified step by step guidance
1
Identify the structure of ATP (Adenosine Triphosphate), which is a nucleotide composed of three main components: a nitrogenous base, a sugar, and phosphate groups.
Recognize that the nitrogenous base in ATP is adenine, which is a purine base.
Understand that the sugar component in ATP is ribose, a five-carbon sugar, not deoxyribose which is found in DNA.
Note that ATP contains three phosphate groups, which are linked in a chain and are responsible for the molecule's energy storage capability.
Compare the given options with the known structure of ATP: adenine, ribose, and three phosphate groups, to identify the correct components.
