Course information

Content and learning outcomes

Course contents *

Models and equations describing the transport of water, ions and nutrients within cells and through cell membranes. Active and passive transport. Channels and carriers. Cell electrical potential (graded and action potential). Methods for measuring cellular physical parameters.

Lectures (24 hours), laboratory exercises (32 hours), hand-in assignment

Laboratory exercises:

  • measurement of diffusion in an aqueous solution that mimics cytoplasm (fluorescent microscopy)
  • measurement of diffusion in cell membranes (living cells, confocal microscopy)
  • measurement of changes in cell volume (living cells, confocal microscopy)
  • measurement of changes in cell membrane potential (living cells, confocal microscopy)

Intended learning outcomes *

Upon completion of the course, students should be able to:

  • describe the basic physical principles of cell function in transport of water, ions and nutrients
  • define mathematical models for transport of water, ions and solutes in and across the cell membrane
  • describe how the cell regulates water and ion balance and how it is affected by the cell environment
  • calculate the cell membrane potential and how it varies in different situations
  • perform measurements of different cellular physical parameters using microscope-based methods
