What Happens to an ATP Molecule After It Has Released

Question

What happens to an ATP molecule after it has released a phosphate?
A) It becomes AMP and is recycled into proteins.
B) It is phosphorylated and becomes ADP.
C) It is converted into lactic acid and transported to the liver for disposal.
D) It is secreted in urine as a waste product of cellular respiration.

Accepted Answer

After ATP releases a phosphate, it becomes ADP (Adenosine diphosphate). This is because ATP stands for Adenosine triphosphate, meaning it has three phosphate groups. When one of them is released, it becomes ADP with only two phosphate groups.
