Question 1

Is passive transport affected by temperature

Answer 1

• diffusion, facilitated diffusion and osmosis may generally increase in rate as temperature increases
• > active transport may or may not be affected by temperature

-the primary thermodynamic motivator in most passive transport is an increase in entropy

Question 2

What does facilitated diffusion require

Answer 2

• it requires integral membrane proteins to serve as transporters or channels for substrates
• > eg; carrier or channel protein
