A description of membrane structure, depicting a cellular membrane as a mosaic of diverse protein molecules embedded in a fluid bilayer made of phospholipid molecules.
A property of biological membranes that allows some substances to cross more easily than others.
process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
a difference in the concentration of a substance across a distance
transport of a substance across a cell membrane by diffusion
diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
the elastic tension of living muscles, arteries, etc. that facilitate response to stimuli
of or involving muscular contraction in which tension is constant while length changes
(of a solution) having a lower osmotic pressure than a comparison solution
(of a solution) having a higher osmotic pressure than a comparison solution
