Answer:
A. ATP
Step-by-step explanation:
ATP is a molecule that contains three high energy phosphate bonds. These bonds are formed between the phosphate groups in ATP and store energy that can be released and utilized by cells during various biochemical processes. When one or two phosphate groups are removed from ATP, it is converted into ADP (adenosine diphosphate) or AMP (adenosine monophosphate), respectively, resulting in the release of energy. However, ATP specifically contains three phosphate groups and, therefore, has three high energy phosphate bonds.
