Document Summary

Neurons confer the unique functions of the nervous system. Differ based on their structure, chemistry and function. 100 billion neurons (give or take 100 million) Neurons contain the same basic structures as most other cells. Surrounded by a membrane that separates the inside of the cell from the outside. Everything within the cell membrane other than the nucleus is the considered. Contain the chromosomes that confer the heritable material dna. Neuronal membrane and function of the membrane and its associated proteins. Cannot understand the function of the brain without understanding the structure cytoplasm. Cell body usually gives rise to a single axon. Conducts nerve impulse from one neuron to the next. Speed of the nerve impulse is a function of the diameter of the axon. Collective term for all neurites of a given neuron. Site where axon comes in contact with another neuron. Space between the two sides of a synapse.

You study a transmembrane protein that is trafficked through theendoplasmic reticulum but ultimately âlivesâ in the plasmamembrane. Suppose the domain of this protein which is exposed onthe outer face of the endoplasmic reticulum membrane was covalently(and specifically) labeled with a fluorescent dye in a living cell.When the protein is distributed among cellular compartments, wherewould you expect the dye to be located?

Question 7 options:

A) The dye will be on the outer face of the endoplasmicreticulum, on the inner face of the Golgi apparatus, and on theextracellular face of the plasma membrane.

B) The dye will be on the inner face of the endoplasmicreticulum, on the inner face of the Golgi apparatus, and on theintracellular face of the plasma membrane.

C) The dye will be on the outer face of the endoplasmicreticulum, on the outer face of the Golgi apparatus, and on theintracellular face of the plasma membrane.

D) The dye will be on the outer face of the endoplasmicreticulum, on the outer face of the Golgi apparatus, and on theextracellular face of the plasma membrane.

Eukaryotic cells manufacture fibrous cytoskeletal proteins thatfunction in the cytoplasm to maintain cell shape by providingstructural support, move materials within the cell, and move theentire structure. Which of the following predictions about proteinsynthesis, processing, and trafficking applies to the general classof cytoskeletal proteins?

B)	They might travel to the nucleus in a transport vesicle with aspecific zip code.

C)	They would initially contain signal sequences that would allowtheir entrance into the endoplasmic reticulum.
