C
Thymine
D
Uracil
Verified step by step guidance1
Understand that ATP (adenosine triphosphate) is a molecule composed of three main parts: a nitrogenous base, a sugar, and phosphate groups.
Identify the nitrogenous base in ATP, which is a purine called adenine.
Recognize that the sugar in ATP is ribose, not deoxyribose (which is found in DNA).
Note that thymine and uracil are nitrogenous bases found in DNA and RNA respectively, but they are not part of ATP.
Conclude that the key component of ATP related to the energy molecule's identity is adenine, the nitrogenous base.
