1. Recent evidence suggests that serious infection duringpregnancy increases risk for autism and schizophrenia after thechild is born. One prominent hypothesis is that this is a result ofincreased activation of microglia in the developing brain. Which ofthe following would be predicted by this hypothesis?
a. Neurons in the brain would have too many synapses.
b. Neurons in the brain would have too few synapses.
c. Neurons in the brain would not have myelinated axons.
d. The brain would have abnormal blood flow and abnormal bloodbrain barrier permeability.
e. There would be a reduced immune response to pathogens thatenter the central nervous system.
2.You are in the lab and are studying transport of a particularprotein along axons. You perform a pulse-chase experiment to labelnewly synthesized proteins and collect samples from the distal axonat several points in time. You find that the labeled proteinsappear in the distal axon already at your first measurement timepoint, which was at 2 hours. Which of the following is likely aTRUE statement:
a. The protein that you are studying is either a membraneprotein or a secreted protein
The protein that you are studying is a cytosolic protein.
c.The protein that you are studying is being transportedprimarily by dynein.
d. A and C
e. B and C
3.
Which of the following best describes what would happen totransport of vesicles along dendrites if a non-hydrolyzable form ofATP was introduced into the cells?
Nothing would change.
Anterograde movement along microtubules would stop.
Retrograde movement along microtubules would stop.
This manipulation would stop short distance movement intodendritic spines from the dendrite shaft.
All vesicular transport along dendrites would stop.
