1
Q
what makes up the cell membrane?
A
phospholipid bilayer carrier proteins channel proteins glycolipids and glycoproteins cholesterol
2
Q
function of cholesterol
A
reduces lateral (side to side) movement of phospholipid bilayer, stabilising the membrane at high temperatures and preventing leakage of ions and water
3
Q
what is the fluid mosaic model?
A
fluid because the phospholid bilayer moves, and mosaic because proteins and glycoproteins and glycolipids are embedded in it.
4
Q
what is a micelle?
A
a small ball made of a fatty acid and monoglyceride
