Following a real-life example of an infant being prescribed oral rehydration therapy, shows how the treatment with a sugar-salt-water mixture works. Examines the structure of thr enterocyte, its two...
A computer simulation of experiments which may be performed on frog skin ‘in vitro’ to study membrane transport of ions. Introduces the method, apparatus and physiological basis of the experiment and...
A computer simulated of experiments that may be performed on the superior cervical ganglion-nictitating membrane preparation of the cat ‘in vivo’ to teach the pharmacology of ganglionic transmission and...
Shows changes of membrane permeability, ionic fluxes and potentials by means of animated diagrams.
Proteins and lipids are the basic building blocks of membranes as demonstrated in the molecular model. The functional groups possess hydrophilic and hydrophobic areas. Therefore amphipathic molecules arise...
An introduction to the structure and functions of biological membranes: cell structure and organelle; plant and nerve membranes; separation of membranes from cells and their composition; phospholipid...
Biological membranes form a border between the cell organelles and the outside world. Communication and metabolic activity demonstrated by plasmolysis, protoplasmic streaming, secretion, enzymatic processes,...
The physical properties of water and the interface behaviour of amphipathic molecules promote the organisation of distinctive structures as demonstrated in the hydrophobic/hydrophilic behaviour of...
Individual membrane functions depend on special membrane construction blocks among its proteins. A measuring cell is used to produce specific (reconstructed) endowed model membranes and to investigate their...
Lipids from the erythrocyte membrane form micells and bilayers when dispersed. Freeze-fracturing of natural membranes reveal the inclusion of integral proteins. Cholesterine influences the fluidity of the...
