QUESTION 24: Which of the following accurately describes the route a secreted protein would take from synthesis to secretion? Translation in the rough ER (rER), followed by transport through the ER and then the Golgi apparatus, packaging into vesicles in the Golgi, transport along microtubules to the plasma membrane, exocytosis. Translation in the smooth ER, followed by transport through the ER and then the Golgi apparatus, packaging into vesicles in the Golgi, transport along microtubules to the plasma membrane, exocytosis. Translation in the Golgi apparatus, followed by transport through the ER and then packaging into vesicles, transport along microtubules to the plasma membrane, exocytosis. None of the above.
QUESTION 25: Match the route of neurotransmitter signaling in the postsynaptic cell with its description: Fastest form of synaptic transmission - A. Ligand-gated ion channels. Uses amplification via enzymes to provide slower and more sustained modulation of postsynaptic neurons - B. GPCRs and second messenger signaling. Shortcut pathway - C. GPCRs activate G-proteins that gate ion channels.
