Passive and Active Transport Across Membranes Flashcards
1
Q
Passive
A
Does not require direct input of metabolic energy
2
Q
Faciliated Diffusion
Passive
A
- Channel proteins
- Gated
- To allow materials to go through
3
Q
Carrier Proteins
Passive
A
- Whenever a molecule links to a carrier protein, the protein’s shape changes to allow the molecule to move from one area of the membrane to another
- Basically changing its shape to allow the molecule to move through the membrane
4
Q
Osmosis
Passive
A
Diffusion of water molecules through specialized channels
5
Q
Osmotic pressure
Passive, Osmosis
A
Pressure that needs to be applied to a solution to prevent the flow of water across a membrane by osmosis
6
Q
Active
A
Requires Energy
