All living matter is comprised of cells, small compartments
isolated from the environment by a cell membrane and filled with
concentrated solutions of various organic and inorganic compounds.
Some organisms are single-cell, where all life functions are
performed by that cell. Others have groups of cells, or entire
organs, specializing in one particular function. The survival of
the entire organism depends on all of its cells and organs
fulfilling their roles.While the cells are studied by different
sciences, they are seen differently by biologists, chemists, or
physicists. Biologists concentrate their attention on cell
structure and function. What does the cell consist of? Where are
its organelles? What function does each organelle fulfil? From a
chemists' point of view, a cell is a complex chemical reaction
chamber where various molecules are synthesized or degraded. The
main question is how these, sometimes very complicated chains of
reactions are controlled. Finally, from a physics standpoint, one
of the main questions is the physical movement of all these
molecules between organelles within the cell, as well as their
exchange with the extracellular medium. The aim of this book is to
look into the basic physical phenomena occurring in cells. These
physical transport processes facilitate chemical reactions in the
cell and that in turn leads to the biological functions necessary
for the cell to satisfy its role in the mother organism.
Ultimately, the goals of every cell are to stay alive and to fulfil
its function as a part of a larger organ or organism. This book is
an inventory of physical transport processes occurring in cells
while the second volume will be a closer look at how complex
biological and physiological cell phenomena result from these very
basic physical processes.
