Adenosine triphosphate (ATP) transfers energy {ATP cycle}. Cells cannot store ATP. ATP cannot cross membranes.
functions
ATP actively transports, contracts muscle, phosphorylates molecules, makes thioester with acetyl-CoA, makes enols, and makes guanidiene.
metabolism
ATP can break down to adenosine monophosphate (AMP) and pyrophosphate. ATP can break down to adenosine diphosphate (ADP) and orthophosphate. Orthophosphate transfers to arginine or creatinine. Cells regenerate ATP by ADP and orthophosphate oxidation, in respiration pathway or glycolysis pathway.
acidity
At high pH, energy in ATP is less, because electron repulsion is less.
concentration
If ATP concentration increases, energy in ATP is less, because dissociation is less.
magnesium
Magnesium binds to ATP phosphates. If magnesium increases, energy in ATP decreases, because magnesium blocks charges more.
