Entropy and biological systems: experimentally-investigated entropy-driven stacking of plant photosynthetic membranes

Jia, Husen; Liggins, John R; Chow, Wah Soon


According to the Second Law of thermodynamics, an overall increase of entropy contributes to the driving force for any physicochemical process, but entropy has seldom been investigated in biological systems. Here, for the first time, we apply Isothermal Titration Calorimetry (ITC) to investigate the Mg21-induced spontaneous stacking of photosynthetic membranes isolated from spinach leaves. After subtracting a large endothermic interaction of MgCl2 with membranes, unrelated to stacking, we...[Show more]
