1. For each of the following statements regarding protein import into ER Indicate whether it is likely to be true or false. Er likely originated from an aerobic bacterium engulfed by a pre eukaryotic; the signal recognition particle remains associated with the er membrane throughout the import process; most er proteins are fully translated before they are imported into the er; the signal particle is a transmembrane protein in the er Indicate wheater true or false. Uptake of ldl particle requires clathrin; ldl particle are always degraded together with the ldl receptors in the lysosome; in the endosome the ldl particle dissociates from the ldl receptor; a mutation that prevents ldl particle from being digested In the lysosome would cause an increase in cellular cholesterol level; reovvirus enters into the target cell by the fusion of the viral membrane Indicate whether true or false. Lipid synthesis occurs on the inner lipid layer of the er membrane; lipid synthesis occurs in the lumen of the er; newly synthesized lipids remains In the location where they are first synthesizex Protein x is a glycosylated transmembrane protein in the plasma membrane. As it transported through the endomembrane system which side of the membrane should the glycosylated portion of the protein be? Lumen side or cytoplasm side of the er membrane; lumen side or cytoplasm side of the golgi apparatus; lumen side or cytoplasm side of the membrane of transport vesicles; extracellular side or cytoplasm side of the plasma membrane
