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