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
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 does ATP release when it loses a phosphate group?
When ATP releases a phosphate group, it forms ADP (adenosine diphosphate) and releases energy that can be used for cellular processes.
In the Calvin-Benson cycle which can donate phosphate?
In the Calvin-Benson cycle, ATP can donate a phosphate group to regenerate ribulose-1,5-bisphosphate (RuBP) in the regeneration phase of the cycle. This process is vital for the continuation of carbon fixation and the production of carbohydrates.
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.
Does rna have a phosphate group or a hydroxyl group?
RNA has both a phosphate group in its backbone and a hydroxyl group on the ribose sugar in its structure. The phosphate group connects the nucleotides in RNA's backbone, while the hydroxyl group distinguishes RNA from DNA, which has a hydrogen atom in its place.
When a phosphate group is transferred directly from an intermediate to ADP to make ATP the process is called?
This process is called substrate-level phosphorylation. It occurs during glycolysis and the citric acid cycle, where a phosphate group is directly transferred to ADP to form ATP.
How is ATP regenerated from ADP?
One molecule of ADP can be easily formed to make one form of ATP. All you need to do is add one phosphate group to the ADP and ATP is formed.ADP + P + energy --> ATPADP + P + energy --> ATP

Po4 functional group?
Phosphate
Does RNA contain a phosphate group like DNA?
Yes, RNA contains a phosphate group in its backbone, just like DNA. The phosphate group is important for forming the sugar-phosphate backbone that gives RNA its structure and stability.
What is found in a nucleotide?
deoxyribose + phosphate group + cytosine deoxyribose+ phosphate group+ cytosine
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.
What three components make up a dna nucleotide?
A DNA nucleotide consists of a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine). These components are linked together to form the building blocks of DNA strands.
Does rna have a phosphate group or a hydroxyl group?
RNA has both a phosphate group in its backbone and a hydroxyl group on the ribose sugar in its structure. The phosphate group connects the nucleotides in RNA's backbone, while the hydroxyl group distinguishes RNA from DNA, which has a hydrogen atom in its place.
What chemical group is at the end of the 5 prime end of DNA strand?
5' - phosphate group 3' - hydroxyl group
When a phosphate group is transferred directly from an intermediate to ADP to make ATP the process is called?
This process is called substrate-level phosphorylation. It occurs during glycolysis and the citric acid cycle, where a phosphate group is directly transferred to ADP to form ATP.
What binds the phosphate group to the next group?
In a nucleic acid, the phosphate group is bound to the next group (either another phosphate or a sugar) by a phosphodiester bond. This bond forms between the phosphate group's phosphate (-PO4) and the hydroxyl group (-OH) of the next group. The bond is formed through a dehydration reaction, where a water molecule is removed.
