Active Transport
•
Sometimes cells must move material against a concentration gradient – from
*_________________________________*
(It’s sort of like pushing your bike up a hill! – you need ____________________ to get that bike to the
top)
 Active _________________________________________
 Smaller molecules and ions  carried across the membrane by ___________________ that act
like ___________________________________________________
 Examples: _________________________________________________________
Sodium-Potassium Pump
__________________________________ are maintained at a
___________________________________ inside the cell, and ______________________ are
maintained at ________________________________________________ inside the cell
_________________________________ by protein molecules of the sodium and potassium ions is
central to  ______________________________________________________________________
Types of Active Transport: Endocytosis
__________________________________________ must be
transported across the membrane
_____________________________  process of taking materials
into the cell by means of “______________________” or ____________________________, of the cell
membrane
The pocket that forms from the membrane breaks loose and forms a ____________________________
What is the function of the vacuole in cells?
____________________________________________________________________________________
 Two examples of endocytosis:
______________________________  “_________________________________;” extension of
cytoplasm surround particle and package it within a food vacuole ( LARGE MOLECULES!!!)
______________________________ when cells take up liquid from surrounding environment.
----Tiny pockets form along membrane, fill with the liquid, and pinch off to form vacuoles within the cell
Types of Active Transport: Exocytosis
When cells ____________________ a large amount of material from the cell
* Membrane of the vacuole ___________________________________________, forcing the contents
________________ of the cell*

Overview
1. The cell membrane ______________________ what enters and exits the cell. The cell wall provides
__________________________________________________________.
2. Particles move from an area of __________________________________________________ to an
area of _________________________________________________. This process is called
__________________________.
3. _________________________ is the diffusion of water through the
__________________________________________________________________________
4. The cell membrane is _________________________________________ and is made out of
_____________________________________, that is where it gets one of its names:
“__________________________________________________________________”
5. _______________________________________ – extensions of the cell membrane surround a
particle and package it within a __________________________________
6. _______________________________ – tiny pockets form along cell membrane,
__________________________________________, and pinch off to form vacuoles inside the cell
7. ______________________________________ requires energy (______________) but diffusion does
not require energy (_____________________________)
