Abstract
AVELLANEDA BERNAL, D. R and NARANJO MAYORGA, F. A Kinesin Transport Phenomena as a Brownian Motor with Hand-Over-Hand Movement Type. Ciencia en Desarrollo [online]. 2014, vol.5, n.2, pp.173-181. ISSN 0121-7488.
The study of the proteinaceous engines locomotion' mechanism is a current topic of interest, because it allows to explain different cell functions and simultaneously provides engines replications at nanometer scale. This study involves the understanding of stochastic phenomena at microscale in periodic systems with any kind of asymmetry and that are outside of the thermal equilibrium. In this way one system being studied that is out of thermal equilibrium and at the same time, is immersed in a universe with dissipation and generation of white thermal noise, which generates a directed movement and as the transportation phenomenon does, so that the system symmetry or asymmetry conditions are modeled. Since the discovery of Brownian motion, there have been carried out some of the most arduous investigations of the physical processes, that can be interpreted under this phenomenon and under the thermodynamics laws. From the microscopic point of view, the random thermal motion dominates this world and makes thermal fluctuations give rise to Brownian motion and Brownian motors.
