What is the full form of ATP?
Think it through first, then pick an option.
- a Adenosine monophosphate
- b Adenosine diphosphate
- c Adenosine triphosphate
- d Adenosine pentaphosphate
Answer and explanation
Correct answer: c Adenosine triphosphate
ATP = adenosine triphosphate: adenosine with three phosphate groups.
Why the other options are wrong
- a Adenosine monophosphate: Monophosphate means one phosphate; that is AMP, not ATP.
- b Adenosine diphosphate: Diphosphate means two phosphates; that is ADP.
- d Adenosine pentaphosphate: The book has no pentaphosphate form; ATP has three phosphates.
