Document Summary
Proteins: integral: serve as channels, receptors, anchors. Amphipathic- each one associated with tail and head of phospholipid bilayer layer. Because they are both polar and nonpolar- they are put into the bilayer and it is difficult to remove them easily. They are an integral part of the membrane! Many are transmembrane- goes all the way across the membrane (top to bottom: peripheral: impact shape and motility. Polar- only like the heads- they are on the inside part of the cell. Cytosolic surface (in) (same as being in the intracellular fluid) Junctions: for interactions: want them to connect and interact so we can make tissues, organs, etc together, need junctions to form tissues, demonstration: staff on stage, each is a cell. Arms are like their gap channels (like in gap junctions). All link arms- form a gap junction: 1. Gap junction: channels linking two cytosols (intracellular fluid)
