Module 2: Passive Transport Flashcards
1
Q
What is passive transport
A
a type of membrane transport that does not require energy to occur, move through a concentration gradient
2
Q
What are the 3 types of passive transport
A
- Simple Diffusion
- Facilitation Diffusion
- Diffusion through channels
3
Q
What is simple diffusion
A
transport of molecules across the plasma membrane from an area of high concentration to an area of lower concentration
4
Q
What is facilitated diffusion
A
A transmembrane integral protein is necessary to move molecules across the plasma membrane
5
Q
What is diffusion through channels
A
molecules move through protein channels that span the entirety of the plasma membrane, facilitated by a concentration gradient
6
Q
What type of passive transport is osmosis
A
Diffusion through channels
