QUESTION 28 Which of the following describes how a protein is inserted into the ER membrane? OA. It is co-translationally inserted into the ER membrane in its correct orientation by an ER-associated ribosome. OB. It is translated in the cytoplasm by cytoplasmic ribosomes and then carried to the ER in a vesicle OC. It is translated by cytoplasmic ribosomes and then transported into the ER by facilitated diffusion OD. It is inserted in the membrane during translation and then flipped at the plasma membrane to attain its correct orientation. QUESTION 29 Which compartments are topologically equivalent with the Golgi? OA- Nucleus, ER, and endosomes A. OB. ER, endosomes, and lysosomes C-Nucleus and mitochondria D. Extracellular space and cytoplasm O E. Cytoplasm, ER, and plasma membrane QUESTION 30 Which of the following molecules is secreted via the regulated secretory pathway? A Insulin OB. Calnexin C. beta-Tubulin OD. SNARE protein OE. UGGT
