WorksheetsUnit 6: Cellular Membrane & Transport Review
Total questions: 20
Worksheet time: 10mins
What is the function of the cellular plasma membrane?
To keep proteins from coming into and out of the cell
To organize and protect the DNA within the cell
To maintain homeostasis by regulating what crosses the cell membrane
To regulate and maintain what goes into and out of the nuclear membrane
Which of the following is NOT a part of the cellular plasma membrane?
Phospholipid
Cholesterol
Cellulose
Proteins
What are the primary differences between the Passive and Active Transport systems?
Active only happens in living cells and Passive only happens in dead cells
Active requires energy and goes against the concentration gradient
Passive doesn't require energy and goes against the concentration gradient
Active doesn't require energy and goes with the concentration gradient
Using the image of Passive Diffusion, Letter A shows which of the following
Outside of the cell and an area of higher concentration
Inside of the cell and an area of lower concentration
An example of simple diffusion
An example of facilitated diffuision
In class we smelled balloons, this was an example of which of the following?
Osmosis
Facilitated diffusion
Active Transport
Simple diffusion
Why is the cellular plasma membrane explained as a fluid mosaic model?
The membrane is wet and can be modeled using small parts
The membrane is wet, not fixed, and can be modeled
The membrane is not fixed and made of small parts
The membrane is fixed, wet, and made of small parts
Using the image, determine what letter C is labeling
Simple diffusion
Osmosis
Active transport
Facilitated diffusion
When does osmosis occur?
When the concentration of solutes inside and outside of the cell are the same
When the concentration of transport proteins within the cell membrane is higher than water
When the concentration of solutes inside and outside of the cell are different
Osmosis is always happening
True or False. Osmosis will occur if a cell is placed in an Isotonic solution
TRUE
FALSE
The movement particles from an area of high to low concentration is considered which of the following?
Active Transport
Passive Transport
Endocytosis
Exocytosis
If a Red Blood Cell was placed in distilled water, what would happen to the cell?
It would shrivel
It would stay the same
It would shrink and implode
It would swell and burst
Which direction will the water move in beaker B?
From inside the cell to outside the cell
Both inside and outside the cell
Water will not move in any direction
From outside the cell to inside the cell
What type of solution is in beaker A?
Hypertonic
Isotonic
Exotonic
Hypotonic
What are the two transport processes that allow large substances to cross the plasma membrane?
Active and Passive transport
Endocytosis and Exocytosis
Simple diffusion and facilitated diffusion
There are more than two
Which of the following is NOT a part of passive diffusion
Simple Diffusion
Facilitated diffusion
Osmosis
Na+/K+ ATPase pump
True or False, this image is an example of exocytosis
True
False
A solution that has more water outside the cell than inside the cell is considered which of the following?
Hypertonic
Hypotonic
Isotonic
Endotonic
What is label E pointing to in the image provided?
Phospholipid bilayer
Phosphate head
Phospholipid
Cell wall
Which of the following best defines the term, selectively permeable membrane?
The outer layer of the cell that allows small particles to passively transport into and out of the cell
The outer layer of the cell that allows large particles to actively transport into and out of the cell
The outer layer of the cell that allows all substances to easily transport into and out of the cell
The outer layer of the cell that allows certain substances to passively or actively transport across the cell
We used this graph to understand how osmoregulation worked in nematodes, What is one thing we can interpret from this graph?
Mutant worms make low amounts of glycerol
WT worms make high amounts of glycerol
Mutant worms make ~1000 nmol/mg protein of Glycerol
Mutant worms make ~1750 nmol/mg protein of Glycerol
