Faciliated Diffusion

Question 1

Proteins involved in facilitated diffusion:

Answer 1

Carrier & channels

Question 2

What is facilitated diffusion?

Question 3

What process is facilitated diffusion?

Answer 3

Passive = doesn’t use energy.

Question 4

Facilitated diffusion refers to what?

Answer 4

Transport of polar molecules & ions in and out out of a cell.

Question 5

What molecules diffuse by facilitated diffusion?

Answer 5

Polar molecules

Question 6

Factors that affect the rate of facilitated diffusion:

Answer 6

• 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.

Question 7

Differences between active transport & facilitated diffusion:

Answer 7

Active transport= no channel proteins
