Energetics of active transport.
In discussing questions of active transport from the viewpoint of linear nonequilibrium thermodynamics it is in a sense superfluous to acknowledge the influence of Aharon Katchalsky. Suffice it to say that this work, which was carried out in close collaboration with Roy Caplan, was begun when we were both working in Ora Kedem's laboratory in Aharon's Polymer Department at the Weizmann Institute...
متن کاملEnergetics of Coupled Active Transport of Sodium and Chloride
A Clark electrode was used to measure oxygen consumption by the gall bladder, in which there is a direct and one-to-one linkage between active Na and active Cl transport. O2 uptake was reversibly depressed when Cl in the mucosal bathing solution was replaced by a poorly transported anion, such as sulfate. This effect of Cl was abolished by ouabain or in Na-free solutions. When the anion was chl...
متن کاملThe Quantum Statistical Mechanical Theory of Transport Processes
A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
متن کاملEnergetics of proline transport in corn mitochondria.
The mechanism of proline entry into the matrix region of isolated corn mitochondria (Zea mays L. Mo17 x B73) was investigated by measuring osmotically induced changes of mitochondrial size (changes in A(520)) in combination with oxygen uptake measurements. Using NADH oxidation to generate the electrochemical gradient, we have determined that proline transport is stereospecific and that it can b...
متن کاملEnergetics of active fluctuations in living cells.
The nonequilibrium activity taking place in a living cell can be monitored with a tracer embedded in the medium. While microrheology experiments based on optical manipulation of such probes have become increasingly standard, we put forward a number of experiments with alternative protocols that, we claim, will provide insight into the energetics of active fluctuations. These are based on either...
