6
Q
Passive Transport
A
when molecules move from a HIGH concentration to a LOW concentration; requires NO ENERGY (ex. diffusion and facilitated channel)
7
Q
Active Transport
A
when molecules move from a LOW concentration to HIGH concentration; requires energy and a protein carrier (example is the sodium/potassium pump).
8
Q
Facilitated diffusion:
A
when molecule diffuses across membrane with help from a protein carrier.
9
Q
Diffusion
A
when molecules move from high to low concentration until they reach equilibrium; it doesn’t require energy.
10
Q
Things that affect diffusion rates
A

12
Q
Osmosis
A
when water diffuses from high to low concentration thru permeable membrane.
