Factors affecting Permeability Flashcards
1
Q
Increasing Temperature
A
More permeability, more heat energy more furiously taps
Increased energy means more kinetic energy
Phospholipids vibrate further and further apart
2
Q
Increasing ethanol concentration
A
Increasing permablity
Organic solvents like ethanol dissovles phospholipids
3
Q
Increasing sodium chloride concentration
A
Decrease
Sodium attaches to the oxygen atoms on the hydrophilic head of the bilayer
4
Q
Increasing detergent concentraion
A
Increases
Reduces surface tension of phospholipids
