- Made of 2 layers of phospholipid molecules. The phosphate head and carbohydrate tail
3
Q
Cholesterol Molecule

- type of steroid lipid
- keeps cell membrane flexible and fluid
4
Q
Integral Protein
A
These proteins are embedded in the cell membrane
Provides channels for bigger molecules to pass through
5
Q
Peripheral protein
A
These are structural proteins that sit on the inside of the cell membrane
6
Q
