This course will provide the relevant foundations of non-equilibrium thermodynamics required to understand biological processes at the subcellular level.
The biological cell can be considered as open thermodynamic system far from equilibrium that enzymatically controls various different reactions and transport processes across internal and the cytoplasmatic membrane. So understanding open thermodynamic system far from equiibium - is necessary for learning ‘biological cell’.
In this course enzymatic free energy and signal transduction processes will be discussed in detail. It will be shown that all the biological molecular machines, also pumps and motors can be considered to be effective chemo-chemical free energy transducers.
The role of internal dynamics of biomolecules on the activity control of enzymes and the action of molecular machines will be discussed at the end.
