Document Summary
L a s t t i m e i n l e c t u r e 6 . Function cytosol nucleus protein synthesis, many metabolic pathways contains genome, dna, rna synthesis, ribosome assembly endoplasmic reticulum (er) synthesis of lipids, synthesis of proteins. Golgi apparatus lysosomes endosomes mitochondria chloroplasts peroxisomes protein modification, packaging of proteins and lipids degradation of cellular material sorting, recycling. Atp synthesis, apoptosis photosynthesis, atp synthesis oxidation of toxic molecules. Orientation of a protein with respect to the cytoplasm and the interior of membrane- bound compartments is maintained during its travel through the endomembrane system. Er is an inter-connected network of membrane- enclosed tubules and flattened sacs (it is reticular) Interior (= lumen) is separate from the cytosol. Er membrane is continuous with the outer membrane of the nucleus. Functions of smooth er (ser: production of steroid hormones.
