B2.1 Membrane Structure Flashcards
1
Q
What is the phospholipid bilayer?
A
A bunch of phospholipids linked together with a hydrophilic and hydrophobic ends.
2
Q
Properties of phospholipid bilayer
A
It is fluid, proteins can move along it
3
Q
What are integral proteins?
A
Permanently embedded in the phospholipid bilayer, either polytopic or monotopic, they are amphipathic (hydrophobic and hydrophilic regions)
4
Q
What are peripheral proteins?
A
Have a temporary association with the membrane
5
Q
Functions of the membrane proteins?
A
TRACIE
Transport, receptor, anchorage, cell recognition, intercellular joining, enzymatic activity
