0
Q
Factors that matter in permeability
A
Size, charge, polarity
1
Q
Semi permeable
A
Selective. Allows some substances to pass more easily than others
2
Q
Fluid
A
Oily, made up of phospholipids and cholesterol (animal membrane)
Unsaturated
3
Q
Fluid:
Amphipathic
A
Has properties of both hydrophilic and hydrophobic
4
Q
Fluid:
Cholesterol
A
Decrease temperature and help keep membranes fluid.
5
Q
Fluid:
Oily (unsaturated)
A
Decrease temp and help keep membranes fluid
6
Q
Mosaic
A
Collection of proteins
7
Q
Mosaic:
Integral proteins
A
Embedded in the phospholipid bilayer
*protrude out
8
Q
Mosaic:
Integral proteins:
Transmembrane protein
A
Span the whole distance edge to edge of membrane.
9
Q
Mosaic:
Peripheral proteins
A
Found on the surface of phospholipid bilayer
*not embedded
