What the cell membrane is mostly composed of
What are phospholipids
100
Diffusion happens anytime there is a difference in concentration in one place compared to another. This is called what?
What is concentration gradient
100
This is something that is not required for passive transport.
What is energy or ATP?
100
Active transport requires energy in the form of what
What is ATP
100
Substance in which a solute is dissolved
What is solvent
200
This term means it only allows certain materials to go into and out of cell
What is selective permeability
200
During simple or facilitated diffusion, molecules move from a _____ concentration to a ______ concentration
What is high to low concentration
200
This is a transmembrane protein that requires a toll and helps molecules through the membrane.
What is carrier protein?
200
This is when a cell has mass movement of molecules from inside to outside the cell.
What is Exocytosis?
200
Concentration is lower outside than on the inside
What is hypotonic
300
This is the hydrophobic biomolecule portion of the cell membrane
What are lipids?
300
This term is used when diffusion continues until the concentration is equal in the space.
What is equilibrium?
300
This creates a tunnel through which molecules can pass via diffusion.
What are channel proteins?
300
This is the difference between a channel protein and a carrier protein.
What is a carrier protein requires a "toll" like ATP?
300
This type of solution causes a cell to shrink and shrivel
What is hypertonic?
400
This connection between carbons creates a bend in the lipid.
What is a double bond?
400
The movement of water molecules across a cell membrane
What is osmosis?
400
In the potato lab this solution saw a loss in mass for the potato.
What is a hypertonic solution?
400
With the sodium potassium pump how many of each element is pumped in and out
What is three K+ out and two NA+ in.
400
This is the job of an ID Protein
What is to communicate with the outside environment of the cell?
500
This is the term given when cells maintain a stable environment
What is homeostasis (or dynamic homeostasis)?
500
These are a specific type of channel proteins that allow water molecules to get past the hydrophobic middle of a membrane.
What are aquaporins?
500
In the dialysis tubing lab, this could not pass the membrane.
What is starch?
500
This is required for what to happen in the body?
What is Action Potential?
or
What is nerves to send messages?
500
These proteins are responsible for communicating for the cell
What are ID Tags and receptor proteins?
