Active & Passive Transport Flashcards
Active Transport
Requires energy to take place (ATP) Endocytosis and Exocytosis Protein pumps (sodium potassium pump)
Passive Transport
Does not require energy
Diffusion
Osmosis
Facilitated Diffusion
Which process can move molecules from a lower concentration on one side of the membrane to a higher concentration solution on the other side?
Active Transport
Which process does not require energy?
Facilitated Diffusion
What does the word “facilitated” mean
Helped
Exocytosis
Cell gets rid of bad solutes
Endocytosis
Cell brings in good solutes
