Grana formation: entropy-assisted local order in chloroplasts?
Grana formation is a prominent feature of the ultrastructure of chlorophyll b-containing chloroplasts, serving to fine-tune photosynthetic efficiency. This paper examines the physical forces that determine the state of minimum free energy of the chloroplast as manifested by grana formation. In particular, it considers the interplay of van der Waals attraction, electrostatic repulsion and short-range hydration repulsion between thylakoid membranes. In addition to these interactions as...[Show more]
