12. A scientist has engineered a novel glutamate receptor for monitoring excitatory neurotransmission at synapses in neurons. The domain that binds glutamate is in the extracellular space of the synaptic cleft. Which compartments has it traveled through on its way to the plasma membrane? a. the lumen of the ER b. the lumen of the Golgi c. the lumen of intracellular vesicles d. all of the above 13. Connective tissue cells produce extracellular matrix proteins as needed, which are then packaged into vesicles that immediately fuse with the plasma membrane to release the ECM proteins into the ECM. What process is being described? a. regulated secretion b. constitutive secretion C. receptor-mediated endocytosis . d. autophagy e. none of the above
