Membrane Movement Flashcards
1
Q
Active transport
A
Facilitative diffusion (cells use its own energy to get what it wants), moves against concentration gradient
2
Q
Proteins
A
Proteins remain stuck in membrane when trying to get into cell so it stays there and acts as food or channels for transport
3
Q
Diffusion moves faster in a _____ environment
A
Warm
4
Q
What’s osmosis
A
Movement of water across a cell membrane usually from a high concentration to a lower concentration
5
Q
Passive diffusion
A
No energy expended, movement from high concentration to low concentration, normal behavior by gas & liquids
