biology, cell membrane

phospholipid head

polar, hydrophilic

phospholipid tail

non-polar, hydrophobic

plasma membrane

composed of a lipid bilayer, with embedded proteins and surface proteins

passive transport

does not require input of energy, moves with concentration gradient

active transport

does require input of energy, moves against concentration gradient

diffusion

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

facilitated diffusion

integral proteins help move moles that are too large

osmosis

movement of water from an area of high to low concentration through aquaporins

aquaporins

water protein channel

endocytosis

movement of materials in to the cell, low to high concentration

phagocytosis

moving food particles into the cell

pinocytosis

moving liquids into the cell

exocytosis

movement of materials out of the cell

cytolysis

swelling or bursting of cells

plasmolysis

shrinking of cells

glycolipid

name?

cholesteral

name?

carbohydrates

allows cells to communicate with one another, helps cells identify cell types, provides sites for chemical messengers, hormones can attach

cholesterol

provides firmness and prevents membrane from freezing

sugar

what does glyco mean?

integral

proteins that extend across the membrane, moves across the membrane

peripheral

proteins that are attached to either side of the membrane, assists chemical reactions

protein channels

moves smaller molecules into the cell

protein carrier

moves larger molecules into the cell

protein pump

moves molecules out of the cell
