Molecules and transport
Passive transport
Vocabulary
Active transport
Labs that we did
100
This kind of channel can open and close.
What is a gated channel?
100
In passive transport, the cell does not have to spend this.
What is energy?
100
It is a solution outside the cell that has a lower concentration of solute than the cell.
What is a hypotonic solution?
100
It is the molecule that cells spend when they need to spend energy?
What is ATP?
100
It is what our egg did when we put it in corn syrup.
What is swell / get bigger?
200
They are molecules that can help diffusion occur during facilitated diffusion.
What are membrane proteins?
200
It is the diffusion of water across a selectively permeable membrane.
What is osmosis?
200
It prevents plant and bacteria cells from bursting when they fill with water.
What is a cell wall?
200
They are human cells that are able to engulf invader cells by phagocytosis.
What are white blood cells?
200
It is the molecule that did not diffuse across the dialysis tube cell.
What is starch?
300
It is a nonpolar molecule that can cross a phospholipid membrane.
What is oxygen or carbon dioxide?
300
It is what a human cell will do in pure water.
What is swell and / or burst?
300
It is a solution that will cause a cell to lose water.
What is a hypertonic solution?
300
It gets pumped out of a cell by a contractile vacuole.
What is water?
300
It is the hypotonic solution that our egg was in.
What is water?
400
It is a molecule that always diffuses into cells because the cells are always using it.
What is oxygen?
400
Another way to say “from an area of higher concentration to an area of lower concentration”.
What is down a concentration gradient?
400
It is a solution that will not cause a cell to gain water and will not cause a cell to lose water.
What is an isotonic solution?
400
It is the pump that uses 1/3 of our energy when we are at rest.
What is the sodium-potassium pump?
400
It is the hypertonic solution that our egg was in.
What is corn syrup?
500
This kind of molecule can cross a phospholipid membrane.
What is a nonpolar molecule?
500
It is the lack of a concentration gradient.
What is equilibrium?
500
It is a difference in concentration between the inside of the cell and the outside of the cell.
What is concentration gradient?
500
It is a cell using its membrane to surround another cell in order to eat the cell.
What is phagocytosis?
500
It is the molecule that diffused from the dish into the dialysis tube cell.
What is iodine?
