a phosphate
a lipid
hydrophobic
hydrophilic
Diffusion of water is known as
diffusion
osmosis
endocytosis
exocytosis
The cell membrane is also called a
mosaic
patchwork quilt
phospholipid bilayer
cell shield
A protein embedded in the cell membrane is called a/an
phospholipid bilayer
peripheral protein
integral protein
cholesterol
The movement of small particles from a region of high concentration to a region of low concentration is known as (a) .
(a) describes the movement of a substance across a cell membrane against its concentration gradient. This process requires ATP.
(a) describes the movement of a substance across a cell membrane with its concentration gradient. This process does not require energy.
The tail of a phospholipid molecule is
hydrophilic
hydrophobic
amphoteric
amphipathic
A cell is (a) to its environment if the concentration of the solute in the cell is equal to the concentration of the solute outside the cell.
The cell structure that controls which substances can enter or leave the cell is the
cell wall
cholesterol
cell membrane
integral protein
Type of active transport where the cell membrane forms a sac around a macromolecule.
diffusion
osmosis
exocytosis
endocytosis
Phagocytosis is a type of endocytosis that bring liquid particles into the cell.
true
false
If a cell is hypertonic to its environment, the cell will likely
shrivel up
swell (and may burst)
stay the same size
Type of active transport where the cell secretes large substances out of the cell
diffusion
osmosis
exocytosis
endocytosis
Peripheral protein with a carbohydrate attached that is involved in cell recognition and identification.
glycoprotein
channel protein
cholesterol
phospholipid
The (a) model describes the movement and arrangement of the cell membrane.
Type of passive transport where special proteins in the cell membrane help move molecules.
passive transport
facilitated diffusion
diffusion
osmosis
