Document Summary

Glycocalyx: carb groups attached to proteins and lipids; on outside of plasma membrane. Extracellular matrix(ecm)= organized network of material produced and secreted by cells. Ecm many important functions: site for cell attachment, contain regulatory factors (signal) etc. Plant cell walls: cellulose, structual support; protection; contain signals for cell. *see karp 7th ed, pg 27 for the endosymbiont theory* Porins:large channels; when open, membrane is freely permeable. Cristae: increae membrane on sa; rich in phospholipid called cardiolipin . Matrix: high in protein; gel-like; conain ribosomes and dna.
