Cell membrane Flashcards
What type of molecule are phospholipids?
Polar
What is the structure of phospholipids?
Phosphate -head
Fatty acid -tails
Which are hydrophilic a hydrophobic?
Phosphate-hydrophilic
Fatty acid = hydrophobic
What are the ways they arrange themselves?
- Monolayer
- micelles
- Bi layers
- membrane bound compartments
What is the name the structure of phospholipids given.
Fluid mosaic model
What can move around in the layer?
- proteins
- phospholipids
What are glycoproteins?
Carbohydrate attached to protein
What are glycolipids?
Carbohydrate attached to lipid
What do intrinsic proteins do?
Go through both layers of membrane
What do protein channels do?
Allows big or water solvable substances
What is a extrinsic PROTEIN?
Sits in one layer
Which way do the phosphates and fatty acids face?
Phosphate:outwards
Fatty acids: inwards
What’s a useful tip?
Draw layer
What are some phospholipids are some aren’t?
Saturated or unsaturated
What does saturated mean?
Has (C=C) bond and double band
Has kink in structure
