collect sunlight which it converts to sugars (a)
packages proteins for delivery (a)
Identify cholesterol molecule
structure a
structure b
structure h
structure i
Plasma membranes are selectively permeable. This means
anything can pass in and out
the membrane regulates the passage of the material in and out of the cell
glucose cannot enter the cell
cholesterol cannot enter
Which is NOT a function of the membrane?
it forms a selective barrier
it has receptors for chemical messages
it is the control center of the cell
it is involved in self recognition
Small, nonpolar, hydrophobic molecules such as fatty acids
easily pass through the membrane's bilayer
very slowly diffuse through the bilayer
require transport proteins
enter through endocytosis
Define plasma membrane
lipid that helps minimize effects of temperature
only on the outer surface of the plasma membrane and are attached to proteins or lipids; form distinctive cellular markers
flexible boundary of a cell that separates a cell from its surroundings
may extend partway into the plasma membrane, cross the membrane entirely, or be loosely attached to its inside or outside face
Which type of biological macromolecule is the main component of the plasma membrane?
carbohydrate
lipid
protein
nucleic acid
This image is an example of a phospholipid. Which part of a phospholipid is HYDROPHOBIC?
the phosphate "head"
the lipid "tails"
This image is an example of a phospholipid. Which part of a phospholipid is HYDROPHILIC?
the phosphate "head"
the lipid "tails"
Where can carbohydrates be found when part of a plasma membrane?
On the outside of the membrane
On the inside of the membrane
Embedded part of the way into the membrane
Embedded the whole way through the membrane
All of the above
What is the "big idea" of the fluid mosaic model of plasma membranes?
the plasma membrane creates a specialized FLUID that looks like a MOSAIC.
the plasma membrane is a MOSAIC.
the fluid mosaic model is NOT related to the plasma membrane.
a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.
What does "hydrophobic" mean?
water loving, associates with water
water fearing, does not associate with water
a world war II submarine
an example would be solutes like sugar or salt
What does "hydrophilic" mean?
water loving, associates with water
water fearing, does not associate with water
a world war II submarine
an example would be solutes like oil or fat
What property does the phospholipid bilayer give to a plasma membrane?
provides the barrier between the inside and outside of the cell
communicates between cells
conducts electrical impulses in nerve cells
allows cells to bind to each other
The majority of the plasma membrane is composed of ______.
phospholipids
proteins
carbohydrates
cholesterol
