Document Summary

Cytosolic proteins are not modified because it never enters the er or the goli. Exocytosis and endocytosis: vesicles are responsible for transporting materials between com of the endomembrane system, used for secretion to cell exterior and bringing molecules into the cell. Endomembrane system: mitochondria and chloroplasts are not part of this. Mitochondria: were sugars are made into atp and co2. Chloroplast: making sugar from co2 and sun: both have two membranes, both have their own dna or genome that encodes proteins (resemble prokaryotic genomes, have distinct ribosomes than found in the cytosol or rough er (resemble bacterial ribosomes) Biosis: living: energy-transducing organelles, chloroplasts and mitochondria, thought to have been derived from free living prokaryotic cells, mitochondria developed from ingested prokaryotes capable of using o2, chloroplasts developed from. Prokaryotic cell primitive eukaryotic cell (invagination in the membrane create nucleus) -
