This is then cascaded through three more enzymes that act on the chemical and ultimately use the energy stored in it to convert ADP to ATP. At the end, a propionate molecule pops out that can then be ...

Basically, phosphorylation is the process by which ATP is created. A phosphate molecule is added to another chemical called ADP, and voíla: ATP is born.

In the presence of pyrophosphate, ADP-ribose is used by the pyrophosphatase NUDIX5 to generate nuclear ATP. The nuclear source of ATP is essential for hormone-induced chromatin remodeling, ...
