Because it's an "uphill" reaction. Phosphate groups are negatively charged so they don't easily go together.
( a phosphate group is removed.) when the chemical bond between the second and third phosphate groups is broken, creating adenosine diphosphate, a phosphate group, and releasing energy.
The process of ADP gaining a phosphate group to form ATP is called phosphorylation. This occurs during cellular respiration, specifically in the mitochondria, where energy from nutrients is used to add a phosphate to ADP. This conversion is crucial for cellular energy storage and transfer.

ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc. The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO4) or attached to another molecule (e.g. an alcohol). Even more energy can be extracted by removing a second phosphate group to produce adenosine monophosphate (AMP). When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight. Thus the ATP molecule acts as a chemical 'battery', storing energy when it is not needed, but able to release it instantly when the organism requires it.
The major molecule involved in energy release and storage is ADENOSINE TRIPHOSPHATE. It contains a large ADENOSINE molecule connected to three PHOSPHATE groups via PHOSPHATE bond. When the bond that connects one of the three PHOSPHATE groups to the ADENOSINE molecule is broken down, energy is released. The resulting molecule would be ADENOSINE DIPHOSPHATE, one free PHOSPHATE group and energy.

ATP synthase
Adenosine triphosphate (ATP): the energy currency or coin of the cell pictured in Figures 1 and 2, transfers energy from chemical bonds to endergonic (energy absorbing) reactions within the cell. Structurally, ATP consists of the adenine nucleotide (ribose sugar, adenine base, and phosphate group, PO4-2) plus two other phosphate groups. Isaac Adams
Adenosine diphosphate (ADP) combines with a phosphate group to form adenosine triphosphate (ATP). This process occurs during cellular respiration, where energy is stored in the bonds of ATP for later use by the cell.
The energy needed to add a phosphate group to ADP to form ATP comes from cellular respiration, specifically the process of oxidative phosphorylation. During oxidative phosphorylation, energy is released as electrons move down the electron transport chain, which is used to pump protons across the inner mitochondrial membrane. The flow of protons back through ATP synthase drives the phosphorylation of ADP to form ATP.
Adenosine triphosphate (ATP) is a high energy molecule with 3 phosphate groups that a cell uses to extract and store energy from other molecules such as carbohydrates.Adenosine diphosphate (ADP) is a low-energy molecule that is one phosphate group less of an ATP molecule. ADP chemically bonds with a phosphate group to form ATP to function as such.Adenosine monophosphate (AMP) is simply the adenosine molecule bonded to only one phosphate group.
No, the addition of a phosphate group is not called oxidation. Oxidation involves the loss of electrons by a molecule, while adding a phosphate group is a form of phosphorylation, which involves attaching a phosphate group to another molecule.
The phosphate group of the incoming nucleotide joins the 3'-hydroxyl group of the last nucleotide in the growing DNA chain to form a phosphodiester bond.
Energy is stored in ADP through the addition of a phosphate group, forming ATP. When ATP is converted back to ADP, the bond holding the third phosphate group is broken, releasing energy that can be used by cells for various cellular processes. This exchange of phosphate groups allows for the storage and release of energy in the form of ATP and ADP.
When a phosphate group is cleaved from ATP to form ADP, energy is released that can be used by the cell for various biological processes. This process of breaking the bond between the second and third phosphate groups releases energy and results in the formation of adenosine diphosphate (ADP) and an inorganic phosphate molecule.
ATP (adenosine triphosphate) is the compound that, when hydrolyzed, produces ADP (adenosine diphosphate), inorganic phosphate, and energy. This process involves the breaking of one phosphate group from ATP to form ADP and release energy that can be used by cells for various physiological processes.
The purpose of ATP is to store energy. ATP stands for adenosine tri-phosphate, and the energy is mostly stored in the third phosphate bond. ATP is used by cells 24/7 as a form of energy. The purpose of ADP is to have to potential to store energy. ADP stands for adenosine di-phosphate, and when another phosphate is added onto the molecule it is called ATP and will store energy. When ATP releases energy the third phosphate comes off and it becomes ADP.
