Biological Electron Transport Systems [PDF]
Proceedings of the National Academy of Sciences, 1970 The solid-state electrical conductivities of a number of ferredoxin model compounds are reported. For one of these compounds, (KFeS 2 ) n , an electron transfer rate for a 25 Å unit is shown to be at least 1 × 10 8 electrons sec -

Fractional Chemotaxis Diffusion Equations [PDF]
, 2010 We introduce mesoscopic and macroscopic model equations of chemotaxis with anomalous subdiffusion for modelling chemically directed transport of biological organisms in changing chemical environments with diffusion hindered by traps or macro-molecular ...

Transport on a Lattice with Dynamical Defects [PDF]
, 2013 Many transport processes in nature take place on substrates, often considered as unidimensional lanes. These unidimensional substrates are typically non-static: affected by a fluctuating environment, they can undergo conformational changes.

Nonequilibrium Transport Induced by Biological Nanomachines [PDF]
Biophys. Rev. Lett. 17, 51 (2022), 2022 Biological nanomachines are nanometer-size macromolecular complexes that catalyze chemical reactions in the presence of substrate molecules. The catalytic functions carried out by such nanomachines in the cytoplasm, and biological membranes are essential for cellular metabolism and homeostasis. During catalytic reactions, enzymes undergo conformational

Non-equilibrium statistical mechanics: from a paradigmatic model to biological transport [PDF]
, 2011 Unlike equilibrium statistical mechanics, with its well-established foundations, a similar widely accepted framework for non-equilibrium statistical mechanics (NESM) remains elusive. Here, we review some of the many recent activities on NESM, focusing on

A two-lane mechanism for selective biological ammonium transport
eLife, 2020 The transport of charged molecules across biological membranes faces the dual problem of accommodating charges in a highly hydrophobic environment while maintaining selective substrate translocation.

The Need for a Kinetics for Biological Transport
Biophysical Journal, 1973 The traditional theory of transport across capillary membranes via a laminar Poiseuille flow is shown to be invalid. It is demonstrated that the random, diffusive nature of the molecular flow and interactions with the "pore" walls play an important role in the transport process.
