Is Atp A Protein Molecule

While most students study atp as it relates to animal metabolism the molecule is also the key form of chemical energy in plants.

Is atp a protein molecule.

The density of pure atp is comparable to that of water. That is the job of carbohydrates such as glycogen and fats. Atp is an unstable molecule in unbuffered water in which it hydrolyses to adp and phosphate. A number of other small molecules can compensate for the atp induced shift in equilibrium conformation and reactivate pfk including cyclic amp.

Ryan nelson has written a good answer but i wanted to amplify it a little. It is often referred to as the energy currency of the cell and can be compared to storing. And a small protein of 100 amino acid residues. 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. When energy is needed by the cell it is converted from storage molecules into atp. 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. Atp then serves as a shuttle delivering energy to places within the cell where energy consuming activities are taking place.

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. The relationship between atp and protein is a complicated one. Consequently atp is best stored as an anhydrous salt. That is a lot.

The melting point of pure atp is 368 6 f 187 c. Not only does protein synthesis take any energy it amounts to 95 of the energy budget in an e. It s 1 04 grams per cubic centimeter. Adenosine 5 triphosphate or atp is the principal molecule for storing and transferring energy in cells.
