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.
Smoking is one of the major reason of Lung cancer. But one may have cancer even if the individual is not a smoker due to radiation, secondary air pollutants.
