CH. 6 Tour Of The Cell
-
cell fractionation- techninique for studying cell structure and functions, separates organelles from one another

-
Nucleus
nucleus is surrounded by a nuclear envelope with double membrane, nuclear envelope is connected to ER
Nucleus keeps chromosomes and genetics, contains nucleoli, where ribosomal subunits are made, the pores regulate what goes in and out of cell
ribosomes- composed of two subunits, RNA and proteins, can be free or bound to ER
ER- complex network of tubules and sacs, membrane separates ;lumen from cytosol and continues with nuclear envelope
smooth ER- synthesis of lipids, metabolizes carbs, detox of drugs
Rough ER- synthesis of secretary and other protein bound ribosomes and adds carbs to protein to make glycoproteins and produces her membranes
Golgi apparatus- stacks of flattened sacs, has polarity
modifies proteins, carbohydrates of proteins, and phospholipids, sorts gold produce when are rebased in vessicles
