Unit 2: Cells- structure of the cell membrane Flashcards
1
Q
what 5 components make up the cell membrane
A
phospholipids (most abundant), cholesterol, membrane proteins, glycoproteins, glycolipids
2
Q
role of cholesterol in the cell membrane
A
keeps phospholipids from moving too far apart (would cause huge gaps in the membrane and anything could get through)
3
Q
result of too much cholesterol in membranes
A
hardening of the membrane and things can’t move through
4
Q
fluid mosaic model (explain each part)
A
fluid- phospholipids are constantly moving
mosaic- bunch of different things coming together to make something
5
Q
role of glycolipids in cell membrane
A
recognition and attachment
6
Q
role of glycoproteins in cell membrane
A
immune system and signaling
