cell membrane diagram
Terms in this set (15)
spherical ("globe-like") proteins that are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins.
proteins in the membrane whose role it is to pass molecules that cannot go through the membrane
Cholesterol (membrane lipids)
a lipid embedded in the phospholipid bilayer that helps maintain fluidity of the membrane, especially in cold temperatures (only in animals (animals move, plants don't, fluidity...))
Membrane carbohydrates that are covalently bonded to lipids.
The proteins of a membrane that are not embedded in the lipid bilayer used in cell communication, signaling, identification
penetrate the hydrophobic interior of the lipid bilayer, transport molecules
filaments of cytoskeleton
A protein that resides primarily on the inner or outer surface of the phospholipid bilayer which constitutes the plasma membrane of the cell.
alpha helix protein
protein that extends through the membrane and acts as a channel for nutrients entering the cytoplasm; wound like a coil
directed toward the center, avoiding water
Has a hydrophilic head that is attracted to water and a hydrophilic tail
A double layer of phospholipids that makes up plasma and organelle membranes.
Attracted to water
carbohydrates (in membrane)
interact with the surface molecules of other cells, facilitating cell-cell recognition
proteins that have carbohydrates covalently bonded to them
