Types Of Transporters Flashcards
Simple Diffusion
Non polar compounds , down concentration
Facilitated diffusion
Polar compounds down gradient (passive)
Primary active transport
Against gradient requires ATP
Secondary active transport
Against gradient, driven by an ion moving down its gradient
Ion channel
Down gradient, may be gated
ionphore mediated ion transport
Down gradient , encapsulated and transferred through membrane
Sodium potassium pumps K+ and NA+
2K+ moves in and 3 NA+ moves out
Put it in and NA it goes out
Types of secondary transport
Symport and anti port
Symport
Moves both in in the same direction
Symmetric
Antiporter
Moves in opposite directions
Antiparallel
Sodium potassium pump is what type of secondary transport?
Antiporter
Sodium glucose pump is what type of secondary transport
Symporter ( cotransporter )
