Document Summary

In class notes: summary, nuclear structure, structure and functions of endomembrane system: nuclear envelope, Types of ribosomes endoplasmic reticulum, golgi, vacuoles and vesicles: production of membrane glycoproteins, mitochondrial structure. Is found in the cytosol (free ribosomes) and attached to internal membranes (bound ribosomes) of eukaryotes: ribosome structure and function, composed of protein and rrna, made in the nucleus. Large and small subunits in prokaryotes and eukaryotes: eukaryotic ribosome location and function. 50% of the membrane: continuous with the nuclear envelope (er buds o of the nucleus) Lumen refers to the space inside er: smooth er- doesn"t have ribosomes, rough er- has ribosomes. Functions of smooth endoplasmic reticulum: synthesis lipids: eg. phospholipids and steroids, metabolizes carbohydrates, detoxi es poison: (poisons induce production of smooth er- tolerance, stores calcium (especially in muscle cell) Functions of rough endoplasmic reticulum: modi es proteins (add carbohydrates > glycoproteins) (insulin-pancreatic.
