Answer:
The correct answer is <em>A molecule consisting of three phosphate groups, ribose, and adenine.</em>
Explanation:
ATP means adenosine triphosphate, and it is a molecule which has a very important role in energy transfer in the cells. As its name says, it is composed by:
- adenine: a purine base, which is also a component of nucleic acids.
- ribose: a 5-carbon sugar (in contrast to deoxyribose, ribose has a -OH group in place of a -H group in carbon 2)
- three phosphate groups
Notice that adenine bonded to the ribose is called adenosine.
