BIOLOGICAL MEMBRANES Flashcards
1
Q
Roles of glycolipids.
A
helps membranes function as a partially permeable membrane.
2
Q
Roles of glycoproteins.
A
cell-cell communication / drug receptors.-Carbohydrate chain.
3
Q
Roles of intrinsic proteins.
A
Transport molecules across membrane ad lets large / hydrophilic molecules through. - channel proteins.
4
Q
Roles of cholesterol.
A
Provide stability / complete barrier / stop ions and water-like molecules through.
5
Q
Fluid mosaic model.
A
Bi-layer of phospholipids- free to move / hydrophilic heads facing out and hydrophobic tails facing in.
6
Q
Roles of membrane.
A
Allows movement in and out of cells / Allows cell-signalling / Site of biochemical reactions / Allows cell to change shape.
