alleryWhich set of components makes up an ATP molecule?
AAdenine, glucose and two phosphate groups
BAdenine, ribose and one phosphate group
CGuanine, ribose and three phosphate groups
DAdenine, ribose and three phosphate groups
Answer & Solution
Correct answer: D. Adenine, ribose and three phosphate groups
1. ATP is a triphosphate molecule formed from adenosine ribonucleoside.
2. It contains the nitrogenous compound adenine, the pentose sugar ribose, and three phosphate groups.
3. The trap option with two phosphate groups is wrong because ATP is a triphosphate, so it is ruled out.
4. The guanine option is wrong because the base is adenine, not guanine.
5. The glucose option is wrong because the sugar is ribose, a pentose.
