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.

What is needed to add a third phosphate group to ADP to make ATP?
ATP synthase
What combines with a phosphate group to form ATP?
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.
Will water be attracted or repelled by a phosphate group?
Water will be attracted to a phosphate group due to the presence of polar covalent bonds within the phosphate group. The oxygen atoms in the phosphate group will form hydrogen bonds with water molecules, leading to an attraction between the two molecules.
What is given off when the last phosphate is separated from ATP?
When the last phosphate group is separated from ATP (adenosine triphosphate), it releases energy in the form of a phosphate bond. This energy can be used for cellular processes such as muscle contraction, active transport, or biochemical reactions.
What phosphate helps regenerate ATP?
Phosphate groups from phosphocreatine (PCr) help regenerate ATP in muscle cells. When ATP is depleted during high-intensity exercise, PCr donates its phosphate group to ADP to form ATP, providing a rapid source of energy.
When is energy released from ATP?
Energy is released from ATP when the terminal phosphate group is hydrolyzed through the process of ATP hydrolysis. This reaction breaks the high-energy phosphate bond, releasing energy that can be used for cellular processes.
What is needed to add a third phosphate group to ADP to make ATP?
ATP synthase
What combines with a phosphate group to form ATP?
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.
What are ATP ADP and AMP?
ATP (adenosine triphosphate) is the main energy currency in cells, storing and transferring energy needed for many cellular processes. ADP (adenosine diphosphate) is a molecule formed when ATP releases energy by losing a phosphate group. AMP (adenosine monophosphate) is formed from ADP when another phosphate group is removed.
Why must energy be added to ADP and a Phosphate group to form ATP?
Because it's an "uphill" reaction. Phosphate groups are negatively charged so they don't easily go together.
Is an addition of a phosphate group called oxidation?
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.
How is energy stored in ADP and released in ATP?
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.
What happen to ATP if one phosphate is liberated to provide energy to the cell?
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.
What compound when hydrolyzed produces ADP inorganic phosphate and energy?
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.
What 3 molecules combine together to form a nucleotide?
A nucleotide is composed of a nitrogenous base, a five-carbon sugar (such as ribose or deoxyribose), and a phosphate group. These three components come together to form the basic building blocks of nucleic acids like DNA and RNA.
What is phosphate group ATP-ADP cycle?
In the ATP-ADP cycle, a phosphate group is added to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP) during cellular energy production. When ATP is used for energy, it loses a phosphate group and reverts back to ADP. This cyclic process allows cells to store and release energy as needed for various metabolic reactions.
What molecule forms when ATP loses a phosphate?
ADP (Adenosine diphosphate) is formed when ATP (Adenosine triphosphate) loses a phosphate group through hydrolysis.
