What does ATP stand for?

• A. Adenosine Diphosphate
• B. Adenosine Monophosphate
• C. Adenosine Triphosphate
• D. Adenosine Tetraphosphate

Answer: (C)

ATP stands for adenosine triphosphate, the molecule that acts as the cell’s energy currency. It’s made from adenosine (adenine attached to a ribose sugar) with three phosphate groups attached. The energy you hear about being released in cellular processes comes from breaking one of the bonds of the last phosphate group, which converts ATP to ADP and a free phosphate, releasing usable energy for work like muscle movement or active transport. The other options would imply different numbers of phosphate groups—two for diphosphate, one for monophosphate, and four for tetraphosphate—which isn’t how ATP is defined in biology.
