Verified step by step guidance
1
Understand the structure of ATP (adenosine triphosphate), which consists of an adenosine molecule bonded to three phosphate groups.
Recognize that the bonds between the phosphate groups in ATP are high-energy bonds, particularly the bond between the second and third phosphate groups.
Learn that when ATP is hydrolyzed, the bond between the second and third phosphate groups is broken, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi).
Realize that the breaking of this bond releases energy, which is then used by the cell to perform various functions such as muscle contraction, active transport, and biochemical reactions.
Note that the release of energy from ATP hydrolysis is crucial for cellular processes, and it does not result in the production of lipids, oxygen, or glucose.
