Adaptation and Optimization of Biological Transport Networks
Physical Review Letters, 2013It has been hypothesized that topological structures of biological transport networks are consequences of energy optimization. Motivated by experimental observation, we propose that adaptation dynamics may underlie this optimization. In contrast to the global nature of optimization, our adaptation dynamics responds only to local information and can ...

Biological transport processes
1989Transport processes are an integral part of biological function. For example, the energy converting processes which we have discussed in the previous chapters need a continuous supply of substrates and a continuous disposal of products and waste. It is evident that there can be no respiration when there are no means for oxygen and substrates (glucose ...

Inorganic carbon transport in biological systems
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19881. The flux of inorganic carbon (Ci) is an important biological process. 2. CO2 crosses membranes through passive diffusion and, perhaps active transport while HCO3- crosses membranes via facilitated diffusion and active transport mechanisms. 3. Carbonic anhydrase is ubiquitous and enhances the flux of Ci. 4.

Transport Mechanisms of Biological Colloidsa
Annals of the New York Academy of Sciences, 1986An effort was made to distinguish among various mechanisms by which colloidal particles can be transported through liquid solutions. Figures 1-3 provide a visual (Figure: see text) summary of these differences. The various "phoretic" motions (electrophoresis, diffusiophoresis, osmophoresis) differ from sedimentation in that the driving forces operate ...

Passive water transport in biological pores
2002Three kinds of membrane proteins have been shown to have water channels properties: the aquaporins, the cotransporters, and the uniports. A molecular-kinetic description of water transport in pores is compared to analytical models based on macroscopic parameters such as pore diameter and length. The use and limitations of irreversible thermodynamics is
