1
Q

What are the two factors which affect membrane structure?

A

Temperature and solvents

2
Q

What happens to the phospholipids as the temperature increases?

A

The phospholipids will have more kinetic energy and will move more.

3
Q

What does the increased movement of the phospholipids result in?

A

The membrane will become more fluid as it begins to loose its structure

4
Q

How does the increased fluidity of the membrane affect its permeability?

A

The membrane would become more permeable (more easier for particles to cross it)

5
Q

What happens to carrier and channel proteins when the temperature increases?

A

They will become denatured

6
Q

What does the denaturing of the channel and carrier proteins affect?

A

The permeability of the membrane

7
Q

How do less polar organic solvents affect the structure of the membrane?

A

The non-polar solvents are able to enter the membrane and disrupt the position f the phospholipids.

8
Q

What happens if increased organic solvents disrupt the structure of the membrane?

A

The membrane becomes more fluid and more permeable
