During diffusion, when the concentration of molecules on both side of the membrane are the same

they will continue to move in both directions

diffusion of water across the cell membrane

Answers

1
Which cell membrane protein crosses both layers of the phospholipid bilayer?
transmembrane protein
cholesterol
glycocalyx
peripheral protein
2
Which means of particle transport requires no energy?
endocytosis
osmosis
exocytosis
sodium/potassium pump
3
What means that some materials, but not all, can cross or move in or out.
selectively permeable
fluid mosaic
endocytosis
phosholipid bilayer
4
Algae cells are placed in an isotonic solution. Salt is added to the solution, what will happen
They will swell
they will burst
stay the same
shrink
5
If a cell with 60% solute, is placed in a solution with 10% solute, where will water move?
nothing will move
water would enter and leave in equal amounts
into the cell causing it to swell
out of the cell causing it to shrink
6
Which movement of substances through a cell membrane requires energy?
diffusion
osmosis
facilitated diffusion
active transport
7
What is a major difference between facilitated diffusion and active transport?
active transport uses proteins
facilitated diffusion moves molecules through the membrane
facilitated diffusion requires energy
active transport moves substances from low to high
8
Solution C is considered
hypotonic
active transport
isotonic
hypertonic
9
What helps keep the cell membrane flexible?
integral protein
cholesterol
carbohydrate chain
peripheral protein
10
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
water to move out of the cell
solutes to move out of the cell
water to move into the cell
solutes to move into the cell
11
Which of the following is a function of the plasma membrane?
keep the cell wall in place
regulate the movement of material in & out of cell
break down lipids, carbs, and proteins
store water, salt, proteins, and carbs
12
At what point in the process of diffusion is equilibrium reached?
equilibrium can never be reached
when there are more molecules in than out
when there are an equal amount of molecules
when there are more molecules out than in
13
Why is drinking too much water be harmful to athletes?
cells are in a hypotonic solution and will shrink
cells are in a hypertonic solution and will swell
cells are in a hypertonic solution and will shrink
cells are in a hypotonic solution and will swell
14
A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
it will wilt
it will enlarge
it will shrink
it will stay the same
15
Which term best describes the tails of a phospholipid?
contains a phosphate group and attracts water
contains two fatty acids and repels water
contains two fatty acids and attracts water
contains a phosphate group and repels water
16
Explain why more water is moving out the cell than into the cell
more water inside the cell than out
concentration of water outside the cell is too great
more solvent outside the cell than in
more solute in the cell than out
17
Why do plants wilt?
plants don't wilt they get lazy
plant cells are in a hypertonic solution & the cells shrink
plant cells are in a hypotonic solution & the cells swell
the plant cells are sleepy
18
Which of the following is an example of passive transport?
facilitated diffusion
endocytosis
sodium/potassium pump
exocytosis
19
The diffusion of water across a selectively permeable membrane is called
pinocytosis
active transport
osmosis
osmotic pressure
20
Which of the following structures serves as the cell's boundary?
plasma membrane
channel protein
mitochondria
chloroplast
21
Solution B is considered
hypertonic
active transport
isotonic
hypotonic
22
When is dynamic equilibrium reached?
when the molecules are mixed and stop moving
when the rate of change in the solution slows by one half
when there is continuous movement, but no change
when the movement of molecules stops being random
23
What types of materials are expelled from cells during exocytosis?
small molecules such as carbon dioxide
charged ions
water and glycerol
large molecules like hormones
24
During diffusion, when the concentration of molecules on both side of the membrane are the same
they will move into the cell
they will stop moving
they will move out of the cell
they will continue to move in both directions
25
What is osmosis?
there is no such thing as osmosis
sleeping on a textbook and acquiring knowledge
diffusion of glucose across the cell membrane
diffusion of water across the cell membrane
26
Solution A is considered
hypotonic
isotonic
active transport
hypertonic
27
Why is misting fruits and vegetables with water help them look fresh?
vacuoles fill with water due to osmosis
plants do not have a rigid cell wall
water cannot move through the cell membrane
plant cells in a hypotonic solution lose water
28
