The exchange of ADP and ATP generates vital energy: each human being exchanges the equivalent of his/her own mass of ATP every day. The regeneration of ATP in mitochondria thus needs an efficient ...

Adenosine diphosphate (ADP) or adenosine triphosphate (ATP)-containing important biological molecules can modify macromolecules like proteins and nucleic acids to alter their function in the cell.

Here we examine the roles that purines play as extracellular signaling molecules, with a particular focus on ATP, adenosine diphosphate (ADP), and adenosine. The first reports of purinergic ...

The pyruvate dehydrogenase complex reaction is allosterically inhibited when there are high ratios of ATP to ADP, NADH to NAD + and acetyl-CoA to CoA. Allosteric activation occurs when the ratio ...
