Cell Transport Flashcards
1
Q
Cell Membrane (cell transport)
A
function is to be selectively permeable to maintain homeoestasis
2
Q
Homeostasis
A
stable internal enviroment
3
Q
Passive transport/diffusion
A
transport across the cell membrane thta requires no energy cost to cell
4
Q
Osmosis
A
Diffusion of water
5
Q
Facilitated Diffusion
A
Proteins in the cell membrane form channels trhough which certain molecules, such as sugar can pass through
6
Q
Active transport
A
cell uses energy
7
Q
endocytosis
A
Active transport, large particles enter the cell
8
Q
exocytosis
A
Active transport, large particles exit the cell
9
Q
Concentration
A
Example: if the water concentration is low, ther is more salt in the subtance than water
10
Q
Diffusion rule
A
Matter goes with the flow, from high (concentration) to low (concentration)
