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)
