ATP powers most of the endergonic processes in cells.
How the potential energy of the phosphoanhydride bond
of ATP may be used to drive otherwise unfavorable reactions
(Fig. 11) is discussed in this section. This discussion
focuses on three major uses of ATP: the generation of ion
gradients, biosynthesis, and movement.
