D
Thymine
Verified step by step guidance
1
Identify the structure of ATP (Adenosine Triphosphate), which consists of three main components: a ribose sugar, three phosphate groups, and a nitrogenous base.
Recall that ATP is a nucleotide, and nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base.
Understand that the nitrogenous bases in nucleotides can be classified into two categories: purines and pyrimidines. Purines include adenine and guanine, while pyrimidines include cytosine, thymine, and uracil.
Recognize that ATP specifically contains the nitrogenous base adenine, which is a purine.
Conclude that among the given options, adenine is the nitrogenous base that is a component of ATP.
