Document Summary

Phospholipid lipid with polar head and non-polar tail. Aligns itself such that it forms a bilayer with another phospholipid with heads on outside and tails in the middle (hydrophobic) Glycoproteins carbohydrate attached to a protein on exterior of membrane. Used to ide(cid:374)tify cell as (cid:862)self(cid:863) to i(cid:373)(cid:373)u(cid:374)e syste(cid:373) Steroid that helps to maintain the fluidity of the membrane. Increases fluidity of membrane when temperature is low. Integral protein protein that is embedded in the membrane such that one side is exposed to the outside of the cell and the other is exposed to the inside. Involved in relaying signals from outside into the cell. Channel protein a protein that provides a gateway for a substance or substances to enter or exit the cell. Peripheral protein a protein on the cell membrane that is exposed to either the inside or the outside of the cell but not both.
