What type of reaction breaks the bonds that join the phosphate groups in an ATP molecule?
The type of reaction that breaks the bond that join the phosphate group in an ATP molecule is known as a hydrolysis reaction.
ATP (Adenosine Triphosphate)
Adenosine triphosphate (most commonly known as ATP) is a compound that consists of three phosphate groups attached to an adenosine molecule, and it is the body’s main energy source.
For example, ATP is used as the energy source for muscular contraction. Energy is released from an ATP molecule when the bond between the last two phosphate groups is broken, resulting in the formation of an adenosine diphosphate (ADP) molecule.
A phosphate group can then be reattached to an ADP molecule to form another ATP molecule.
