factors affecting membrane stucture Flashcards
1
Q
how does increase in temperature affect the membrane
A
increasing temperature increases the kinetic energy and the molecules move faster.
permeability increases
it affect the way membrane embedded proteins are positioned
2
Q
what happens to membranes as temperatures drop?
A
saturated fatty acids become compressed
the kinks in their tails push phospholipids away maintaining fluidity
3
Q
how do high temperatures affect proteins?
A
it causes them to vibrate breaking hydrogen and ionic bonds
4
Q
effect of solvents on phospholipids
A
organic solvents will damage cell membranes as they dissolve in them
