BIOL 102 Lecture Notes - Lecture 7: Golgi Apparatus, Vacuole, Lysosome
Document Summary
Stores calcium ions the golgi apparatus: shipping and receiving center. Cis face: receiving side from er trans face: shipping side function of golgi apparatus. Sorts and packages materials into transport vesicles. Shipping product out of golgi using vesicles lysosomes: digestive compartments. Primary lysosomes: buds of golgi (not active) Secondary lysosomes: when digesting and fused with food vacuole (active) Break down complex molecules make fuel, degrade foreign molecules. Structure: large vacuoles derived from the er and golgi apparatus functions: variety of functions in different cells food vacuoles are formed by phagocytes. Animals contractile vacuoles pump excess water out of cells. Plants central vacuoles = plant cells, organic compounds and water. Phospholipid bilayers form spontaneously due to shape and amphipathic nature (hydrophilic head, hydrophobic tail) fluid mosaic model: membrane components can move laterally within one layer of the membrane. Carbs fluidity depends on: temperature, chain length of tails & bends in tails, saturation, amount of cholesterol.
