Transport through the Cell Flashcards
What are the 2 types of TRANSPORTS across the cell membrane?
Passive and Active Transport
It moves DOWN the concentration gradient
Passive Transport
It DOES NOT REQUIRE ENERGY
Passive Transport
It REQUIRES ENERGY
Active Transport
It moves AGAINST the concentration gradient
Active Transport
It transports SMALL nonpolar MOLECULES
Passive Transport
It ALWAYS NEEDS PROTEIN CARRIERS
Active Transport
It refers to the DIFFUSION of WATER
Osmosis
Mention the 3 examples of Passive Transport.
Simple Diffusion
Osmosis
Facilitated Diffusion
Mention the 3 examples of Active Transport
Na + K + Pump
Endocytosis
Exocytosis
__________ is when a cell EXPELS a VESICLE’S content to the EXTERIOR of the cell
Exocytosis
2 fluids, separated by a membrane, that have the SAME overall CONCENTRATION of SOLUTES
Isotonic
When the fluids have different concentration of solutes, the one with LOWER ONCENTRATION is called:
Hypotonic
When the fluids have different concentration of solutes, the one with HIGHER CONCENTRATION is called:
Hypertonic
_________ is the movement of molecules from a higher to a lower concentration
Diffusion
