Faciliated Diffusion Flashcards
1
Q
Proteins involved in facilitated diffusion:
A
Carrier & channels
2
Q
What is facilitated diffusion?
A
3
Q
What process is facilitated diffusion?
A
Passive = doesn’t use energy.
4
Q
Facilitated diffusion refers to what?
A
Transport of polar molecules & ions in and out out of a cell.
5
Q
What molecules diffuse by facilitated diffusion?
A
Polar molecules
6
Q
Factors that affect the rate of facilitated diffusion:
A
- Number of carrier proteins =↑=↑ rate
- Speed of individual carrier proteins= ↑ = ↑ rate
- Availability of ATP and rate of respiration in cell = no respiration= no energy = no active transport.
7
Q
Differences between active transport & facilitated diffusion:
A
Active transport= no channel proteins
