What is the exterior of Anmimal Cell Made of?
-a Glue material made of proteins and proteins modified with sugars(RER)
-Not rigid
Glycocalyx "sugar coat",
-Cushions the plasma membrane and protects it from chemical injury
-Binds cells together so that tissues do not fall apart
Tight Junction
-Series of proteins that interlock and prevent extracellular material from infultrating
-Barriers
Desmosomes
-"Fuzzy Rivets" protein material that rivets cells together
Gap Junctions
-Similar to Plasmadesmata
-little pores that allow the penetration of small solutes from one cell to the next(communication channels between the cells.
Fibronectin
-a high-molecular-weight extracellular matrix glycoprotein containing about 5% carbohydrate that binds to membrane spanning receptor proteins called integrins. In addition to integrins, they also bind extracellular matrix components such as collagen, fibrin and heparan sulfate.
Collagen
is the main protein of connective tissue in animals and the most abundant protein in mammals, making up about 50% of the whole-body protein content.
