BI110 Lecture Notes - Lecture 8: Nuclear Membrane, Phospholipid, Cyanobacteria
Document Summary
Contains the nuclear envelope, er, golgi complex, Then sorts finished proteins to be secreted from the cell or embedded. It chemically modifies proteins made in the rough er in the plasma. Insures that transportation through vesicles to other cells is filled with the correct proteins. Used for storage, breakdown of waste products, and other specialized functions. Form from vesicles, which are phospholipid membrane and hold its between the lipid heads. Allows for transportation between the endomembrane system. Absorbs sun light to chemically alter that energy in the form of light into organic molecules. Both mitochondria & chloroplasts have their own ribosomes. Energy-transducing organelles, chloroplasts and mitochondria, are derived from free-living prokaryotic cells. Different bacterial cells that contained theses organelles were engulfed by a larger organisms and stayed alive in the organisms for a long period of time which allowed the host cell to produce energy and food. Mitochondria developed from ingested prokaryotes capable capable of using o2 for aerobic resp.
