The Thermodynamic Machinery of Life

The Thermodynamic Machinery of Life presents the relevant foundations of nonequilibrium thermodynamics as applied to biological processes taking place at the subcellular level. The biological cell is considered as a complex open thermodynamic system far from equilibrium that enzymatically controls various biochemical reactions and transport processes across internal and the cytoplasmatic membrane. The enzymatic free energy and signal transduction processes are described in detail. All the biological molecular machines, also pumps and motors are considered to be effective chemo-chemical free energy transducers. Special attention is paid to the role of the mesoscopic internal dynamics of biomolecules in the activity control of enzymes and the action of molecular machines.

A must for all biophysicists and cell biologists as well as interdisciplinary interested physicists and chemists Includes supplementary material: sn.pub/extras

Klappentext

Living organisms are open thermodynamic systems whose functional structure has developed and been kinetically frozen during the historical process of biological evolution. A thermodynamics of both nonequilibrium and complex systems is needed for their description. In this book, the foundations of such a thermodynamics are presented. Biological processes at the cellular level are considered as coupled chemical reactions and transport processes across internal and the cytoplasmic membrane. All these processes are catalyzed by specific enzymes hence the kinetics of enzymatic catalysis and its control are described here in detail. The coupling of several processes through a common enzyme is considered in the context of free energy or signal transduction. Special attention is paid to evidence for a rich stochastic internal dynamics of native proteins and its possible role in the control of enzyme activity and in the action of biological molecular machines.
