Answer:
There is no label attached but the question can be answered based on general knowledge
C. points to the bonds between P and P
Explanation:
Adenosine triphosphate, commonly known as ATP, is the energy carrier molecule in living cells. ATP is structurally composed of Adenine molecule (a nitrogenous base), Ribose (pentose sugar) and three phosphate groups.
Energy in ATP is stored in the bonds that hold the phosphate groups together. This energy in ATP is released when the bond that holds the last phosphate group is broken leading to a release of energy and a phosphate group. This converts the ATP to ADP (adenosine diphosphate).
Hence, points to the bonds between P and P is the label that identifies the part of the ATP molecule that changes when energy is released in the cells of all living things.
