CELL RECEPTORS

• Structural and functional properties of receptors and their classification, cell surface receptors, endocytotic pathway and intracellular movement, classification

• Signaling pathways often have a cascade architecture which result in strong signal amplification.... Signal transduction is the biochemical

Signal molecule located on surface of signaling cells or on extracellular matrix.. Types of

Most extracellular signal molecules bind to specific membrane receptors....

Major classes of surface (MEMBRAN) receptors

• Increase in cytosolic Ca2+ concentration activates proteins required for the vesicle membrane to fuse with the plasma membrane and release the vesicle contents into

The diploid number for humans is 46 (46 chromosomes per cell)...

relatively simple cells - lack nuclear membrane and many organelles - bacteria and their relatives are all prokaryotic3. ___________ cells - more complex cells - have a
