Homeostasis
Stable internal environment

phosphate heads are
polar, hydrophilic

lipid tails are
nonpolar, hydrophobic

receptor proteins
help the cell sense its environment

transport proteins
help move substances across the cell membrane

Enzymes
help with chemical reactions inside the cell

Protein Doorways
Large particles enter the cell through these

concentration gradient
difference in the concentration of a substance from one location to another

concentration
the amount of substance in a certain area

Equilibrium
molecules moving randomly to evenly fill a space

Diffusion
Movement of molecules from an area of higher concentration to an area of lower concentration.

Osmosis
Diffusion of water through a selectively permeable membrane

passive transport
the movement of substances across a cell membrane without the use of energy (ATP) by the cell

active transport
the movement of materials through a cell membrane using energy (ATP)

Diffusion is complete when particles reach
equilibrium
Bi-layer
two layers

cell membrane
thin, flexible barrier around a cell; regulates what enters and leaves the cell

Semi-permeable
membranes that allow some substances through but not others

Phospholipids
Cell membrane is made of these.
