Dispersal
Select all of the following that are considered passive transport:
Diffusion
Active Transport
Facilitated Diffusion
Osmosis
Creating the H+ ion concentration gradient for ATP synthesis
Active Transport requires the input of _______________.
Energy

Physical Movement
Food
What type of transport involves the natural movement of molecules from high to low concentrations?
Diffusion
Active Transport
Dispersal
Potassium Ion Channel
What type of transport involves the movement of molecules from a low to high concentration?
Diffusion
Osmosis
Facilitated Diffusion
Active Transport
What type of transport is shown in the diagram? Molecules are being moved across the membrane with the help of a protein.
Diffusion
Facilitated Diffusion
Active Transport
Osmosis
True or False: In Osmosis, water will always flow towards the direction of the solute.
True
False
Look at the diagram. Why does the water flow from the left side to the right side?
There is a physical force pushing it through the membrane
Active Transport is occurring to move the molecules against the concentration gradient
There is a lower concentration of water molecules on the right side, so the natural flow from high to low is occurring
The solute on the right has a charge that attracts water molecules
What is a solute?
The molecule with a higher concentration in a solution
The molecule that is smaller in a solution
The molecule with the lower concentration in a solution
Any molecule dissolved in water, no matter the circumstances
Why is the cell membrane considered to be selectively permeable?
It allows all molecules to pass through
Molecules are only allowed to go through the membrane through a channel protein
It allows only some molecules to pass through but not others
The cell membrane is not selectively permeable. The information in the question is completely false
What molecules cannot pass through the cell membrane on their own? Select all that apply
Polar molecules
Nonpolar molecules
Molecules without a charge
Cholesterol
Any lipid
The picture is an example of...
active tranport
passive transport
diffusion
osmosis
Identify the following structure
Phospholipid
Cell
Cell membrane
Protein
What is the main difference between active and passive transport?
Active transport requires energy, while passive transport does not.
Passive transport requires energy, while active transport does not.
Both require energy.
Neither requires energy.
