This course is dual-listed with BPH 405. This course is concerned with fundamental theory and principles of various kinetic processes underlying the normal function of biological systems and membrane transport processes in biological systems. Topics include chemical kinetics, thermodynamics and statistical mechanics, osmotic forces, membrane permeation of non-electrolytes and electrolytes, membrane transport and various ionic channels in excitable cells, membrane bulk transport and intracellular vesicle trafficking processes. Theories and principles developed to the state of current research knowledge are discussed.
