Nucleotide exchange from ADP to ATP is crucially important for both the regulation and motility of the molecular motor kinesin 1,2,3,4,5. At least three key events occur during this step.

The enzymatic removal of a phosphate group from ATP to form ADP releases a huge amount of energy which is used by the cell in several metabolic processes as well as in the synthesis of ...

Energy is released from ATP when the end phosphate is removed. Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule. ADP can be recharged back into ...

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.

During cellular respiration, energy is captured when a phosphate is added to ADP (adenosine diphosphate ... requires six separate ATP-driven steps; while convincing models do allow for prebiotic ...

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 ...

Besides being functionally defective, the platelets were smaller than normal and contained reduced amounts of adenosine triphosphate (ATP) and ADP. A population of prematurely senescent platelets ...
