CAMBRIDGE, England â British scientist Stephen Hawking has decoded some of the most puzzling mysteries of the universe but he has left one mystery unsolved: How he has managed to survive so long with such a crippling disease.
Brownian movement. n. 1. (General Physics) random movement of microscopic particles suspended in a fluid, caused by bombardment of the particles by molecules of the fluid. First observed in 1827, it provided strong evidence in support of the kinetic theory of molecules.
The rectification of those Brownian events is done by the small molecule exchange of ATP for ADP. The energy that drives that process is what's important. The switching operation that involves acceptance or removal of a phosphate controls a protein's affinity for binding to other proteins it encounters as Brownian motion moves it through cells.
