Passive transport Flashcards
1
Q
What is passive transport
A
When a cell spends no energy of adenosine triphosphate (ATP) to move molecules
2
Q
Where do cells move?
A
Cells move from high to low concentration.
3
Q
Types of passive transport:
A
- Diffusion
- Osmosis
- Facilitated diffusion
4
Q
What is diffusion
A
Diffusion is the movement of molecules from an area of high to low concentration without the expenditure of energy (ATP)
5
Q
What is equilibrium
A
Equilibrium is the even balance of molecules. This is how many molecules move into and out of cells
6
Q
What is osmosis
A
Osmosis is the diffusion of water through a selectively permeable membrane from a less concentrated solution to a higher concentrated solution.
7
Q
What is distilled water.
A
100% H2o, no solutes
8
Q
What is salt water
A
High solutes (mostly salt)
