Because the membrane bound ATP Synthase protein uses high energy to bond adenosine diphosphate (ADP) and phosphate (P) into adenosine triphosphate (ATP) and this requires a lot of energy because it is very difficult to bond another P to ADP (Already has two). This is why it's used as a energy molecule, because it can easily release high amounts of energy.
ADP-ATP is endergonic and B-C is exergonic
Energy is usually released from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate- oxygen groups, leaving adenosine disphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent. Then the ADP is usually immediately recycled in mitochondria where it is recharged and comes out again as ATP.
After ATP hydrolysis, ADP is formed as a byproduct. This process releases energy that can be used by the cell for various functions.
If ATP hydrolysis is not coupled to cellular work, the energy released from hydrolysis cannot be used to drive essential cellular processes such as active transport, muscle contraction, or biosynthesis. This can lead to a lack of energy for vital cellular functions and ultimately result in cell dysfunction or death.
The delta G value in the hydrolysis of ATP indicates the amount of energy released or required during the reaction. This value is important because it determines whether the hydrolysis of ATP is energetically favorable or not. If the delta G value is negative, it means that the reaction releases energy and is spontaneous, which is crucial for cellular processes that require energy.
Condensation is the process where ADP and inorganic phosphate combine to form ATP, while hydrolysis is the reverse process where ATP is broken down into ADP and inorganic phosphate, releasing energy. These are key reactions in energy metabolism where ATP serves as the primary energy currency in cells.
making ATP is endergonic. This is because after ATP hydrolysis to form ADP + P, we now are at a lower energy state and for ATP to be formed again it has to be fueled by catabolic pathways, eg respiration. this energy input allows ATP to be formed and thus we see that phosphorylation of ADP requires energy input (endergonic) to form ATP. Converting ATP into ADP and P itself is EXERGONIC.
Exergonic reactions release energy and are spontaneous, while endergonic reactions require energy input and are non-spontaneous. ATP is used to drive endergonic reactions by providing the necessary energy for them to occur. ATP is regenerated through exergonic reactions by capturing the energy released during these reactions.
The hydrolysis of ATP is an example of an exergonic reaction, releasing energy stored in the phosphate bonds. This released energy can be used to drive cellular processes such as biosynthesis, muscle contraction, and active transport.
The free energy change of the hydrolysis of ATP to ADP is around -30.5 kJ/mol under standard conditions in the cell, making it an exergonic reaction that releases energy. This energy is utilized to drive various cellular processes.

ATP
This reaction is a hydrolysis reaction, specifically the hydrolysis of ATP into ADP and inorganic phosphate (Pi). It releases energy stored in the high-energy bonds of ATP.
False. It cannot be exergonic considering the nature of the pyranose ring, a strong structure that requires high pressures and temperatures in order to break it. There is a reference from 1995 [Glucose hydrolysis and oxidation in supercritical water. AIChE Journal, 41, 637 (1995)] where the authors detail the hydrolysis and oxidation of glucose in supercritical water at 246 bar and at 425 to 600ºC. On the other hand, in metabolic conditions, glucose undergoes the glycolysis pathway, a series of transformations from glucose to pyruvate in order to enter the Krebs cycle and to produce ATP in oxidative phosphorylations thereafter. The final balance of glycolysis (from glucose to ATP) is exergonic, that's the reason of why the body (in higher organisms) generates heat.
Yes, hydrolysis reactions often require the input of ATP to break down molecules by adding a water molecule. ATP provides the necessary energy to drive the hydrolysis reaction by breaking the bond between the molecules in the presence of water.
The release of energy, inorganic phosphate (Pi) being a product, and ADP being formed are all typical outcomes of ATP hydrolysis. The formation of more ATP would not occur during ATP hydrolysis.
