Questions and Answers

What is the main role of the Golgi apparatus in a neuron?

  • Breaks down waste products using enzymes
  • Collects, packages, and distributes proteins synthesized in the rough ER (correct)
  • Produces energy sources that cells can use
  • Detoxifies drugs and poisons
  • Where is the action potential primarily generated?

  • Axon (correct)
  • Dendrites
  • Axon terminal
  • Synapse
  • What is the unique characteristic of axons in terms of protein synthesis?

  • Proteins in the axon are produced in the mitochondria
  • Proteins in the axon are made at the synaptic terminals
  • Proteins in the axon are only made in the cell body and then transported to the axon (correct)
  • Proteins in the axon are produced in the Golgi apparatus
  • Which part of the neuron contains no microtubules but numerous synaptic vesicles and mitochondria?
