1
Parts of the cell membrane
Cell membrane
Proteins
Lipid bilayer
Carbohydrates
Transport protein
Phospholipids
2
The cell membrane regulates
What enters and what leaves the cell
3
What does the cell membrane do for the cell
Regulates what enters and leaves the cell
Provides protection and support for the cell
4
The proteins are embedded in the
Lipid bilayer
5
The lipid bilayer gives the membrane a flexible structure that forms a
Strong barrier between the inside and the outside of the cell
6
Many of the proteins form what to help move materials across the membrane
Channels and pumps
7
The carbohydrates serve as...
Identification makers to help individual cells to identify one another
8
Homeostasis:
A balance that organisms maintain through self-regulating adjustments
9
Cell membrane is also called...
A selectively permeable membrane or a semipermeable membrane
10
What can the cell membrane control
Can decide what can come into the cell
Can decide the speed they are allowed to enter
11
In the concentration gradient in the absence of other forces, materials will tend to...
Move from an area of high concentration to an area of lower concentration
12
When an equal amount of concentration has been achieved it is called
Equilibrium
13
Passive transport definition
No energy is being used to move molecules across the membrane
