Document Summary
Membrane bound nucleus, larger than bacterial/ and archaeal cells, contain organelles, posses a cell wall and complex internal cytoskeleton. Plays role in storage and expression of information, double membrane structure, linear chromosomes of cell, non membrane bound nucleolus exists within nucleus (ribosome synthesis) Spatial separation: transcription nucleus, translation cytoplasm. Uses er/golgi apparatus (extocytosis): proteins are often modified in these structures prior to reaching their destinations. Proteins orginate from the dna in the nucleus of the cell. Mitochondria (power house basic metabolism occurs here) Uses electron transport chains to produce atp (chemiosomosis) Use electron transport chain atp (chemiosomosis) Phospholipid bilayer (contains proteins) molecule transport. Eukaryotes: cholesterol (fatty) keep cell together [bacteria do not, some have hopanoids like cyano family) Specific b-1-4-glycosidic bonds between sugars, provides strength and rigidity. Composed of microtubules, microfilaments, intermediate filaments (rmbr blocks & motor) Involved in intercellular trafficking, motion, and cell division (via fluorescent microscopy)
