question 15 of 25
where is the chemical energy stored in atp?
the ribose sugar that is unstable due to its ring - shaped structure
the hydroxyl groups that react with other molecules to release energy
the purine base that is unstable when attached to the ribose sugar
the multiple nitrogen atoms in adenine that attract each other
the phosphate groups that repel each other due to multiple negatively charged atoms

Explanation:

ATP (adenosine - triphosphate) has three phosphate groups. The negative charges on the oxygen atoms of these phosphate groups cause them to repel each other. Breaking the bonds between these phosphate groups releases energy. The energy is stored in the high - energy phosphate bonds due to the electrostatic repulsion of the negatively charged phosphate groups.

Answer:

the phosphate groups that repel each other due to multiple negatively charged atoms
