1What are the 4 membrane protein types:
Integral - Polar and Nonpolar Regions
Surface - Anchored in the membrane, keeps them attached to the exterior and interior surface.
Channels and Carrier Molecules - Moving molecules in and out of the membrane, safe passage.
Receptors - Signaling molecules triggering a signal from outside to inside.
Enzymes
2What are CAMS?
Cell adhesion molecules, important in forming tissue
General structure less specialized
3What are recognition proteins?
Markers for tissues, cells any endemic molecule contain to prevent removal. Used in immune system.
4Explain carbs?
Found exclusively in exterior surface facing out of membrane
Outer surface of plasma membrane
Used in cell recognition, recognizes "self"
5What is the process of cell to cell adhesion simplified to?
Binds cells into tissue/organs
6What holds cells together?
Excellular matrix is a meshwork of fibrous proteins that holds cells together.
7What are desmosomes?
Adhering junctions used in tissues subject to stretching.
8Tight junctions
Seals off passageway between 2 cells in direct contact.
9Gap junctions
Connects cytoplasm of adjaecent cells to allow for connection.
