Answer:
A
Explanation:
The structure of ATP is such that there are three (3) phosphate moelcules in sequence attached to the 5’ carbon of the ribose sugar ring. The O- groups of each phosphate are close to each other and are negatively charged. They, therefore, repel each ohtehr electrostatically and make ATP very unstable – hence considered weak bonds. ADP is more stable than ATP. Nonetheless, phosphoanhydride bonds between the phosphate have high energy of ΔG of -30.5 kJ/mol. These characteristic make ATP ideal as ane energy currency since it is easy to hydrolyze while producing much energy.
