Which of the Following Contributes to the Instability of ATP

Question

Which of the following contributes to the instability of ATP?
A)demand by the cell to use phosphate in other chemical reactions
B)insolubility of adenine in water
C)weak ionic bond
D)weak covalent bond
E)repulsion between phosphate groups

Accepted Answer

The repulsion between phosphate groups contributes to the instability of ATP by making the phosphoanhydride bonds (the bonds between the phosphate groups) more susceptible to hydrolysis, which releases energy for cellular processes. The other options are not factors that contribute to the instability of ATP.
