Bio 151 1nd Edition Lecture 6 Outline of Last Lecture - Prokaryotic Cells- Eukaryotic Cellso Nucleus o Endomembrane system Traffic patterns Exocytosis/endocytosis Degradation and recyclingOutline of Current Lecture - Endomembrane systemo Traffic patternso Exocytosis/endocytosiso Degradation and recycling- Cytoskeletono Filament typesCurrent Lecture- Endomembrane system: nuclear bilayer that envelops the nucleus- Endoplasmic Reticulum (ER): site of integral membrane and secretion (going outside) protein synthesiso Also site of membrane assemblyo 2 types: Smooth ER (sER): no ribosomes; site of lipid synthesis; synthesis of fat-soluble molecules (steroid hormones); detoxification center (alcohol) Rough ER (rER): with ribosomes, ribosomes come in two forms:- Free: make protein destined for cytosol- Bound: associated with rER, make membrane secreted proteinsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Exit in the form of vesicles Golgi materials enter at cis face materials worked on in sacs and exit at trans face sorting happens at trans facetraffic patterns diverge vesicles fuse with plasma membrane exocytosis materials enter cell wall (Endocytosis) lysosomes/vacuoles degradation and
