BIOL 2021 Lecture Notes - Lecture 6: Osteopetrosis, Peroxisome, Lysosome
Document Summary
Feb 4 biol2021: v type atpase ** Genetic disease (bone densirt increase bond become stiff. Intercellular compartments and protein sorting ch 12: the key to the eukaryotic cell is compartmentalization. Increase surface area of membrane and allow for functionally specialized space. Lysosome contains a lot of degraded products so it looks like dark: compartmentalization is by membrane-enclosed organelles. Organelles: parts with specialized function many membrane bound lumen = interior of membrane-bound organelle (er ) 2: all eukaryotic cells have the same basic set of membrane-enclosed. Rough er protein modifications (transition by ) Smooth er lipid synthesis, detox(liver has a lot of it) glycosylation. Golgi - receives lipids and proteins from the er for modification, sorting and transport to endomembrane system or secretion. Lysosomes digestion (macromolecules degradant old organelles) Endosomes from endocytosis old organelles. Peroxisomes oxidation reax fatty acids. Plastids manufacturing and storage organelles in plants and some protists(food or plasmid storage), including chloroplasts (photosynthesis)
