The rate of the lateral diffusion of straight-chain phospholipids predicts the rate of water diffusion through bilayers. A new model of lipid dynamics integrates these processes. Substances such as cholesterol that reduce water diffision proportionally reduce lateral diffusion. The model yields a number of predictions about the dynamics of the lipids at the T,,, and suggests different mechanisms for how water diffuses across bilayers of other-thanstraight-chain lipids, and how proteins bind to membranes. A second recent development in water transport across biological membranes is the discovery of a ubiquitous family of water transport proteins that facilitate large-volume water translocation. Like water diffusion through lipid bilayers, water transport by these proteins is directed by osmosis and is therefore under the control of ATP and ion pumps. The presence of water transport proteins in membranes is often regulated by hormones.

“…In the interstitial space, excess H + also combines with HCO 3 − to form CO 2 and water. Excess CO 2 which diffuses readily through cell compartments 12,16,28 quickly enters blood. CO 2 also diffuses into astroglial cells to be rapidly hydrated to carbonic acid by carbonic anhydrase 11,17,23,44,45 .…”

“…CO 2 is a highly diffusable gas in tissues (Krogh, 1919;Gleichman et al, 1962;Kaethner and Bangham, 1977 ] lost is equal to the change in P t(CO 2 ) multiplied by S ′ ). Our results show that peak P t(CO 2 ) increased linearly with lactate content until lactate reached about 17 mmol/kg.…”
