Biology Cell Transport
Test Description: Passive and Active Transports
Instructions: Answer all questions to get your test result.
1) Which of the following pieces of evidence would suggest that a substance entered a cell via active transport as opposed to passive transport?
A
ATP was required for transport
B
the substance moved across the membrane via a carrier protein
C
the substance moved from a high concentration to a low concentration
D
none of the above
2) Active transport is a way for molecules to move across the plasma (cell) membrane. When active transport is used to move molecules, what is required?
A
very small molecules
B
energy that the cell provides
C
concentration gradient
D
osmosis
3) Substances transported by facilitated diffusion
A
move passively through specific channels from an area of greater concentration to one of lower concentration
B
are limited to solvents
C
must have movements coupled to those of other substances
D
may flow to a region of higher concentration by the expenditure of energy
4) A lipid bilayer
A
actively transports water soluble molecules through it
B
permits water soluble molecules to pass through it
C
inhibits the passage of water soluble substances through it
D
facilitates the passage of water soluble molecules through it
5) Exocytosis is a process by which cells
A
pass substances out of the cell in vesicles
B
release substances directly into the extracellular fluid through a pore
C
pass substances out of the cell through the membrane by osmosis
D
release substances directly into the extracellular fluid through a pit
6) The methods of membrane transport that don't require protein channels or carriers are
A
osmosis
B
all of the choices
C
phagocytosis
D
diffusion
7) What is the main function of a selectively permeable membrane?
A
Regulates what enters and leaves the cell
B
Breaks down molecules within the cell
C
Storage of chemicals
D
Storage of water
8) Which of these would be least likely to diffuse across the phosopholipid bilayer of a cell membrane?
A
carbon dioxide
B
sodium ions
C
Water
D
oxygen
9) The sodium-potatsium pump is an example of
A
osmosis
B
diffusion
C
active transport
D
facilitated diffusion
10) The carrier molecules used in active transport are
A
calcium pumps
B
protein
C
lipids
D
carbohydrates
11) A red blood cell will lyse (or burst) when placed in which of the following kinds of solution?
A
hypotonic
B
hypertonic
C
isotonic
D
none of the above
12) Wilting of a plant occurs
A
if the plant is placed in an isotonic solution
B
when a plant with flexible cell walls is placed in a hypertonic solution
C
if there is a rise in turgor pressure
D
as a result of facilitated diffusion
13) Diffusion occurs
A
only through a lipid bilayer membrane
B
from an area of high concentration to an area of low concentration
C
from an area of low concentration to an area of high concentration
D
only in liquids
14) Sugar molecules can enter cells through the process of
A
facilitated diffusion
B
osmosis
C
exocytosis
D
ion pumps
15) Molecules that are too large to be moved across a cell membrane can be removed from the cell by
A
endocytosis
B
osmosis
C
facilitated diffusion
D
exocytosis
