ATP stands for Adenosine Triphosphate. The bond between the __________ (first, second, or third) phosphate group and the _______
polet [3.4K]

Answer:

The bond between the _second_________ phosphate group and the third__phosphate group is a high energy bond.

Explanation:

Adenosine triphosphate is a nucleotide with three phosphate groups.  The second and third phosphate groups are bonded by high energy covalent bonds to the rest of the ATP molecule, which consists of a sugar, which is ribose, the first phosphate group, and the nitrogenous base which is adenine. All of the phosphate groups are negatively charged and repel each other, so a high energy covalent bond is necessary to attach these phosphate groups together and keep the forces from pulling them apart.
