WebThe phosphoanhydride bonds of ATP, or the bonds between phosphate molecules, are high energy. This is due to the close proximity of positively charged phosphate and negatively charged oxygen; these charges repel. Also, there is resonance stabilization of the products of ATP hydrolysis (ADP and Pi); thus ADP is more stable than ATP.

[Solved] Why does the phosphate ion have resonance 9to5Science

WebThe two oxygens are both partially negative, this is what the resonance structures tell you! While both resonance structures are chemically identical, the negative charge is on a different oxygen in each. This is important because neither resonance structure actually exists, instead there is a hybrid. WebCreatine phosphate is the main high-energy, phosphate-storage molecule of muscle. In rested muscle, creatine phosphate is the predominant form (Demant and Rhodes, 1999 ); its maximal concentration is five times higher than that of ATP.
