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

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.

Biological Transfer and Transport Processes
2018This chapter explores the biological processes that will be discussed with respect to four major classes of marine contaminants: heavy metals, artificial radionuclides, chlorinated hydrocarbons, and petroleum hydrocarbons. Obviously, much more is known about biological transport for some types of contaminants than others, and this is reflected by their
