Cell membranes control what _____________ the cell to maintain an internal balance called ________
enters and exits
Phospholipids are the modified so that a _______(PO4-) replaces one of the three fatty acids normally found on a lipid. The addition of this group makes a _________________
polar head and 2 non polar tails
In passive transport, molecules spread out from an area of ____ concentration to an area of ____ concentration
What are four types of passive transport
the solution has a lower concentration of solute and a higher concentration of water than inside of the cell
Whats the result of hypotoncic
water moves from the solution to inside the cell. cell swells and bursts open(cytolysis)
Whats the result of the hypertonic cell
water moves from inside the cell into the solution. the cell shrinks. c plasmolysis
the concentration of solutes in the solution is equal to the concentration of solutes inside of the cell
Whats the result of being isotonic
water moves equally in both directions and the cell remains the same size(dynamic equilibrium)
How do bacteria and plants cells deal with osmosis pressure
they have cell walls that prevent them from over-expanding. In Plants the pressure exerted on the cell wall is called turgour pressure
How do protist like paracieum deal with osmosis pressure
has contractile vacules that collect water flowing in and pump it out
membrane proteins similar to carrier proteins transport ions from high to low concentration
How do the ions get through
because they cant pass through the nonpolar part of the lipid bilayer so they are shielded by protein channel
taking bulky material into a cell
-cell membrane in-folds around particle
-forms vesicle/vacuole around particles
