27 views6 pages

Document Summary

The cell as the fundamental unit of life. Al cells have certain basic features: lipid bilayer plasma membrane, cytoplasm (cytosol, dna based chromosomes, rna, ribosomes. Defining feature is the lack of internal membranes. General structure: cell wall/capsule, plasma membrane, cytosol, nucleoid body, ribosomes. General structure: plasma membrane, cell wall, cytosol, endomembrane system, organelles, cytoskeleton. Molecules must enter and leave the nucleus through large protein complexes called nuclear pores. Nuclear envelope supported by an internal array of structural proteins: nuclear lamina. Nucleolus: lots of rna and proteins, ribosome assembly. Interconnected membranous organelles: nuclear envelope, endoplasmic reticulum, golgi, vesicles, vacuoles and endosomes. Rough er has attached ribosomes: synthesis of secretory glycoproteins, synthesis of intramembrane proteins, synthesis of phospholipids, bulk assembly of new membranes. Cis face: closer to the er, receiving side of the golgi. Trans face: facing plasma membrane, shipping side of the golgi. Distribution center of the cell: receives molecules from er, modifies molecules then adds tags ( zip codes )
