Co-transport + Bulk transport Flashcards
What provides the energy for co-transport
Molecules or ions moving down their concentration gradient
how do molecules and ions provide energy for co-transport
bc moving down concentration gradient is an energetically favorable process. This can be coupled to an energetically unfavorable process
What are the two types of carrier proteins in co-transport
Antiporters, Symporters
Whats an antiporter
Where the ion moves in opposite direction to the actively transported molecule
Whats a symporter
Where the ion moves in the same direction as the actively transported molecule
What is bulk transport used for
Extremely large substances
Two types of bulk transport
Endocytosis and Exocytosis
What is endocytosis
the bulk transport of material in to the cell
What is Exocytosis
the bulk transport of material out of the cell
