Detailed explanation-1: -In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.

Detailed explanation-2: -ATP stores energy within the bonds between phosphate groups, especially the second and third. This bond is a source of potential chemical energy, and it’s kind of like a compressed spring.

Detailed explanation-3: -The ATP synthase (or F1F0 ATPase and also referred to as complex V) uses the free energy of an electrochemical gradient of protons (or sodium ions) generated by the respiratory chain to synthesize ATP.

Detailed explanation-4: -ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy.

Detailed explanation-5: -ATP is synthesized by the enzyme F1F0-ATP synthase. This enzyme, the smallest-known molecular machine, couples proton translocation through its membrane-embedded, hydrophobic domain, F0, to the synthesis of ATP from adenosine diphosphate (ADP) and inorganic phosphate (Pi) in its soluble, hydrophilic headpiece, F1.
