Factors affecting membrane structure Flashcards
1
Q
What holds fatty acid tails together in different phospholipids?
A
Weak intermolecular forces
2
Q
How does temperature effect phospholipid bilayers?
A
- Forces vibrate faster
- Break at too high temperature
- Phospholipids break apart
- Protein carrier denature
- Permaebility increases as bigger gaps between phospholipids, simple diffusion
3
Q
What are non polar solvents
A
- Insert themselves into the bilayer
- Disrupt forces and bilayer
- Big gaps increasing permaebility and fluidity
- Eg. ethanol
