Release of the solute from the binding site induces a conformational change that returns the protein to its initial shape. This process does not require any energy input; in fact, a concentration gradient itself is a form of stored (potential) energy, and this energy is used up as the concentrations equalize. a-A vesicle inside the cell fuses with the plasma membrane and releases its contents outside the cell. ln(Ps)=24.513T5892.5K, ln(Pl)=17.3573479KT\ln(P_l)=17.357-\dfrac{3479 \text{ K}}{T} Seattle, Washington(WA), 98106.
