phospholipid bilayer

Lipid involved in cell recognition and cell signaling.

Attached to the exterior surface of the cell membrane

Integral proteins are embedded within the cell membrane and have a role in the transport of molecules across the membrane.

Stabilizes membrane during temperature changes.

Protein that plays a role in cell recognition and signaling.

proteins that let water through

rigid wall found in plant cells

movement of particles from an area of high concentration to an area of low concentration

Using a protein to passively transport molecules across the membrane - commonly used with channel proteins

Requires ATP to to move molecules against the desired concetration gradient

taking water and macromolecules into a cell by folding them into the bilayer and removing a portion of it to form a vesicle

Taking in vesicles to the bilayer and remocing molecules

higher concetration of solute

lesser concetration of solute

potential energy of water to preform osmosis

equal concetration

total concetration of all solutes in a organism

A storage vacoule used to hold water that will be expended later as a cell might need to have a higher concetration than that of the outside
