cells
Cell membrane
Allow certain things to pass through it
They protect your cells
Diffusion
Simple and Facilitated
The way that cells get past the membrane
Channel proteins
Usually with the concentration gradient
Help large polar molecules get into the cell
Cholesterol
Inside the bi-layer
Help keep the cell membrane stable
Transport protein
Requires ATP
It goes against the concentration gradient
Osmosis
Goes with the concentration gradient
Diffusion of water
Isotonic
Same amount of water inside and outside the cell
Cell doesn’t change
Hypertonic
More solutes inside and cell
More water outside the cell
Hypotonic
More water inside the cell
There are more solutes outside the cell
Endocytosis
The cell uses it to take in huge molecules
Uses it to bring in or take out molecules and proteins
