5.3 Active Transport Flashcards
1
Q
Active transport
A
mechanisms require the cell’s energy, usually in the form of adenosine triphosphate (ATP)
2
Q
electrochemical gradient
A
a combined electrical and
chemical force that produces a gradient
3
Q
pumps
A
Active transport mechanisms,
4
Q
Primary active transport
A
moves ions across a membrane and creates a difference in charge across that membrane, which is directly dependent on ATP.
5
Q
transporters
A
specific carrier proteins or pumps to facilitate
movement
6
Q
uniporter
A
carries one specific ion or molecule.
7
Q
symporter
A
carries two different ions or molecules, both in the same direction.
