Chapter 8 - Biological Membranes Flashcards
1
Q
Micelle
A
Mono layered
2
Q
Liposomes
A
Bilayered vésicules
3
Q
Waxes
A
Class of lipids that are extremely hydrophobic
Long chain fatty acid and long chain alcohol
4
Q
Gap junctions
A
Direct cell to cell communication
*also called connexions
**permit movement of water and some solutes directly between cells
5
Q
Tight junctions
A
Prevent solutes from leaking into space between cells
- found in epithelial cells
- function as physical link between the cells as they form single layer of tissue
6
Q
Des osmoses
A
Bind adjacent cells by anchoring to their cytoskeletons
7
Q
Nernst equation
A
E = RT/zf ln([ion]out/[ion]in)
Use this: ***
E = 61/z * log (out/in)
