double membraned and contain
DNA?
50 Prokaryotes and Eukaryotes 1

Cell Transport 1
How are the phospholipids
arranged in the cell
membrane?
10
Cell Transport 1
As a bilayer*phosphate heads facing the
outside and inside of the cell
*fatty acid tails facing each
other
20
Cell Transport 1
*What is the role of
Cholesterol in the cell
membrane?
20
Cell Transport 1
*Stabilizes the cell
membrane
*prevents the cell
membrane from freezing
at low temperatures.
30
Cell Transport 1
What makes the cell
membrane a Fluid Mosaic?
30
Cell Transport 1
Fluid- *fatty acid tail kinks prevent the
phospholipids from packing too tightly,
*cholesterol prevents cell membrane from
freezing at low temperatures
Mosaic- the arrangement of all of the
various molecules in the cell membrane
resemble a mosaic
40
Cell Transport 1
What are the functions of the
cell membrane?
40
Cell Transport 1
*regulate what moves in
and out of the cell/
semipermeable
*allows cell to attach to
other cells and surfaces
*immune response
*makes up organelles
50
Cell Transport 1
What influences the movement
of molecules across the cell
membrane?
50
Cell Transport 1
*size, charge, polarity, concentration, and the permeability
of the cell membrane

<MCecowski#NoSpam.sif.com.ar>
Q: if both a bear in Yosemite and one in
Alaska fall into the water
which one disolves faster?
A: The one in Alaska because it is
HIJKLMNO
10 Population Growth
Alimentary: What Sherlock Holmes said to Dr. Watson.
Urinate: What a nurse would say if a patient asked her what room
he's in.
Urine - The opposite of "You're out!"
Benign: What we want when we are eight.
Intestine - Currently taking an exam
CARDIOLOGY: advanced study of poker playing
TERMINAL ILLNESS: getting sick at the airport
10
What is diffusion?
Cell Transport 2
10
Cell Transport 2
*passive transport of molecules across
the cell membrane
*must be small and nonpolar

Cell Transport 2
An animal cell in a hypertonic
solution will..
20
Cell Transport 2
*shrivel up
30
Cell Transport 2
Upon drinking salt water, what kind of
condition are you creating for your cells?
What will happen to them?
30
Cell Transport 2
*the outside of the cells will be hypertonic
compared to the inside of the cells.
*your cells will lose water, shrivel up, and
become dehydrated.

Cell Transport 2
What are the three types
of endocytosis? Explain
each.
40
Cell Transport 2
*the cell membrane pinches in around the
molecules to enter the cell and forms a vesicle,
which is brought into the cell.
*Phagocytosis (solid)
*Pinocytosis (liquid)
*receptor-mediated (highly specific)
50
Cell Transport 2
How is active transport different than passive transport?
50
Cell Transport 2
*molecules move from low to high concentration
*against the concentration gradient
*requires energy
*includes the simple model, endocytosis (phagocytosis,
pinocytosis, and receptor-mediated endocytosis) and
exocytosis.
