Document Summary
Day 2 er remakes the n envelope in t phase. after it is destroyed in m/a phase. golgi, membrane bags near er. lyso/endo some. bags. single membrane sec. gran. made in golgi. different types. The power house of the cell chloroplast, double membrane. third membrane? peroxisome -> not learning. Ribosome, rna protein complex. in cytoplasm, phoc or chloroplast nucleolus, extensive gene expession cytoskeletal -> protein complexes. Membranes have lipids and proteins, lipids are hydrophobic and the proteins are hydrophilic. They form phospholipids, which then create a bilayer, with the lipids on the inside and the proteins exposed to liquid. The membrane is constantly in motion, if still then mem cracks and the cell dies. Membranes evolved with the pro, and was passed down to the eu. Fatty acid : has a hydrophilic head, and a phobic tail. Micelle is a sphere made of fatty acids. Liposome is a hollow sphere, heads out on both sides, tails inside the bilayer.
