Title

C14 - Organization by convection in cell-free cytoplasm

Description

This image depicts dynamics of pattern formation reaching a higher level of complexity as a convective flow joins diffusion as a transport mechanism. If, e. g., surface forces, as they are caused by gradients in concentration and/ or temperature (mostly induced by evaporation), get off balance, the lower layers of the solution often arrange themselves in surprisingly regular patterns in the millimeter range. The bright and dark lines in the picture mark the boundaries of so-called convection cells, where streams of the liquid moving in different directions encounter. In these regions the mixing of substances is more pronounced and therefore matter transport is increased, “stimulating” the chemical reaction, as shown in picture C18.
C14 gives an impression of the effects which convection may exert on cell-free cytoplasm of yeast in which metabolic turnover takes place.
