Cells and Cell Processes Notes
•
The main goal is to _______________________________________________
•
___________________________________________________________________________________________
___________________________________________________________________________________________
•
Provides a _____________________ on which specific __________________________ can occur.
•
Site for _________________ containing specific ____________________________ markers that differentiate
one cell from another.
•
____________________________ from one another.
•
______________________________ the inside of the cell.
•
The membrane doesn’t completely protect the cell because many substances that aren’t beneficial to the cell
can still enter through _______________________.
•
Membranes allow cells to create and maintain internal environments that differ from external environments.
•
______________________________________________________________
–
Permeability depends on:
1. ___________________________________
2. ___________________________________
3. Charge (ions)
4. Presence of channels and transporters
The cell membrane is often referred to
as the “FLUID MOSAIC MODEL”
• A membrane that is a fluid structure
(can move easily), with a “mosaic” of
various proteins and carbohydrates
embedded in it.

General Structure
•
•
•
•
Phospholipids are made up of a ________________________________________________ and
____________________________________________________
The _________________________ makes up the ____________________ of the lipid bilayer
and the _______________________ _______________make up the
___________________________.
Proteins that extend through the entire membrane are called amphipathic; they have both
hydrophilic and hydrophobic regions.
Along the membrane, many ______________ and _________________ are attached to
____________________. Together they function in ______________________ and
______________________________.
