Is Atp A Protein Molecule

The melting point of pure atp is 368 6 f 187 c.

Is atp a protein molecule.

Atp is an unstable molecule in unbuffered water in which it hydrolyses to adp and phosphate. Ryan nelson has written a good answer but i wanted to amplify it a little. It is the main energy currency of the cell and it is an end product of the processes of photophosphorylation adding a phosphate group to a molecule using energy from light cellular respiration and fermentation all living things use atp. It s 1 04 grams per cubic centimeter.

That is a lot. The density of pure atp is comparable to that of water. That is the job of carbohydrates such as glycogen and fats. Adenosine triphosphate also known as atp is a molecule that carries energy within cells.

You can make atp by burning protein that you eat you need functional proteins to help in the process of building atp and proteins can break down atp. Atp is highly soluble in water and is quite stable in solutions between ph 6 8 and 7 4 but is rapidly hydrolysed at extreme ph. Consequently atp is best stored as an anhydrous salt. Atp is a chemical energy molecule that your cells use to provide for their fuel needs.

While most students study atp as it relates to animal metabolism the molecule is also the key form of chemical energy in plants. The relationship between atp and protein is a complicated one. Atp is not a storage molecule for chemical energy. The protein has two binding sites for atp the active site is accessible in either protein conformation but atp binding to the inhibitor site stabilizes the conformation that binds f6p poorly.

And a small protein of 100 amino acid residues. A number of other small molecules can compensate for the atp induced shift in equilibrium conformation and reactivate pfk including cyclic amp. Atp then serves as a shuttle delivering energy to places within the cell where energy consuming activities are taking place. When energy is needed by the cell it is converted from storage molecules into atp.
