Cellular Housekeeping Flashcards
What is the role of the rough ER?
It synthesizes new proteins destined for plasma membrane or beyond
What is the role of the Golgi Apparatus?
It physically assembles these proteins
What is the role of free ribosomes?
They synthesize proteins intended for the cytosol
What is the role of the smooth ER?
It synthesizes steroid hormones and lipoproteins, modifies hydrophobic compounds into water-soluble molecules for transport
What is the role of a lysosome?
They contain degradative enzymes that permit digestion of proteins. polysaccharides, lipids and nucleic acids
What is the role of a Proteasome?
They chew up denatured proteins, releasing peptides
What is the role of a Peroxisome?
They breakdown fatty acids - generating hydrogen peroxide in the process
