Flashcards in Simple Transport Deck (20):
Movement of molecules
What are the two types of diffusion?
Movement of water passed a membrane
Movement of solutes (everything else) passed a membrane
What are the three types of dialysis?
Movement of molecules along concentration gradient
Movement of molecules through a membrane along a concentration gradient
Movement of molecules through a membrane by use of a carrier molecule (protein) along concentration gradient
Where does passive go through?
Passive dialysis goes through blue balls.
If it can't go through, it's called facillitated
Movement of solutes across a membrane "against" concentration gradient by use of atp
Only energy source for cell
How many types of active transport are there
Movement of large amounts of solutes OUT of the cell whereby the transport molecule becomes part of the plasma membrane after releasing its contents
movement INTO the cell
How many types of endocytosis are there?
Cell eating ; PACMAN
Portion of the cell plasma membrane surrounds incoming substance then fuses with a lysosome (stomach cell)
Cell drinking ; FLY EATING
Substance is dissolved outside the cell and then enters as i did in phagocytosis
Incoming substance can only enter if there is a receptor sight within plasma membrane that it bonds to, allowing a transport vesicle to form
What are enzymes made of
