Verified step by step guidance

Understand the structure of ATP: ATP (adenosine triphosphate) consists of an adenine base, a ribose sugar, and three phosphate groups labeled alpha (α), beta (β), and gamma (γ).

Identify the types of bonds present in ATP: ATP contains phosphoanhydride bonds between the phosphate groups, an ester bond between the ribose and the alpha phosphate, and a glycosidic bond between adenine and ribose.

Recognize the role of ATP in energy release: ATP releases energy when a phosphoanhydride bond is broken, typically between the beta (β) and gamma (γ) phosphates, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi).

Eliminate incorrect options: The hydrogen bond between adenine and water is not relevant to ATP's energy release. The ester bond and glycosidic bond are not involved in the energy release process.

Conclude that the phosphoanhydride bond between the beta and gamma phosphates is the bond broken to release energy, as this is the primary mechanism by which ATP provides energy for cellular processes.
