Cell Membrane Flashcards
Cell membranes is made up of? (3)
Phospholipids, proteins, and steroids
The have hydrophobic part of a phospholipid
Tails
The hydrophilic part of phospholipid
Head
The tails can either be saturated or unsaturated also knows as…
Not kinky or kinky
What does an unsaturated tail provide in the fluid mosaic model?
Space
What does the saturated tail mean in fluid mosaic model?
Less space for fluid to go in
What steroid can control in bilayer of a cell, and what does it do?
The steroid cholesterol can provide space for fluid to go in and out of cell.
Help with identification, communication, and immune responses
Glycoproteins.
Think: “The green on top of the purple in fluid mosaic model”
Helps with movement of the cell so it can go around. (Type of protein)
Glycolipids help with movement
What can easily go in cell with not facilitates diffusion or active transport?
Small no polar molecules
What has a hard time going into the cell?
Big polar molecules or big molecules in general.
Why can water easily go into cells?
Because of the small portions it goes into cells even though it’s polar.
