Detailed explanation-1: -The entropy, which is the level of disorder, of ADP is greater than that of ATP. Therefore, due to thermodynamics, the reaction spontaneously occurs because it wants to be at a higher entropy level. Also, the Gibbs’ free energy of ATP is higher than that of ADP.
Detailed explanation-2: -A phosphate is released into the cytoplasm and energy is released. ADP is a lower energy molecule than ATP, but can be converted to ATP by the addition of a phosphate group.
Detailed explanation-3: -What happens to the entropy when ATP is hydrolysed to ADP? B. Entropy decreases.
Detailed explanation-4: -The difference between ATP and ADP is primarily due to the three factors like their energy state, the number of phosphate groups and the hydrolysis process. ATP is comparatively a high energy molecule than the ADP.
Detailed explanation-5: -ATP hydrolysis provides energy and it couples with a reaction producing negative entropy.
