Document Summary
Endomembrane system: organelles all interconnected with membranes: nucleus: Nuclear lamina: proteins on inside, provides structure and shape, nucleolus: Assembly site of ribosomal subunits: rrna coiled up with ribosomal proteins, endoplasmic reticulum: Smooth er: lipid synthesis, calcium storage, detox, lots in liver, ovaries, testes (lipid hormones) Thursday, october 6, 2016: ribosomes bound to membrane making it rough , synthesis of proteins. Secreted/inserted into membranes (glycoproteins: makes membrane, lots in pancreas. Transitional er: vesicles containing proteins bud from here. Form into transport vesicles after detachment: golgi apparatus: Site of protein modi cation, labeling, and transportation. Ups of the cell: cis face- receiver, trans face- shipper, lysosomes: Perform either: phagocytosis- cell eating , digesting macromolecules, can kill bacteria, autophagy- self eating breaks down damaged organelles. Organelles not part of endomembrane system: mitochondria: Double membrane, with lipid bilayer and proteins: ribosomes: Bound- bound to er or nuclear envelope; proteins inserted into membranes or.
