Cell transport Flashcards
1
Q
Homeostasis
A
Maintaining a balance internally despite what is going on externally
2
Q
What maintains homeostasis
A
The cell membrane
3
Q
How does the cell membrane maintain homeostasis
A
By controlling the passage of molecules (water, salts, food particles, etc.) in and out of the cell
4
Q
passive transport
A
when molecules move from an area of high concentration to an area of low concentration until equal; NO energy
5
Q
Diffusion
A
The process by which molecules spread from areas of high concentration, to areas of low concentration
6
Q
Facilitated diffusion
A
When substances move from high to low concentration using channel/carrier proteins located in the membrane
