Document Summary

Also known as golgi body or golgi complex, this organelle seems to look like stacked sacs of enclosed membranes. This can only be found in eukaryotic cells. Its location in a cell is in the cytoplasm; near the endoplasmic reticulum and the nucleus. It chemically modifies and sorts proteins as well as lipid molecules that come from the endoplasmic reticulum. It synthesizes glycoproteins and glycolipids by adding carbohydrates to the proteins and lipids it receives. It packages the modified products into vesicles for transport to lysosomes, the plasma membrane, or outside of the cell. Cells would not be able to equip proteins and lipids for transmission to places within or outside the cell. This would have a negative impact on various organs of plants and animals. Lysosomes form on the golgi apparatus, so without the golgi, there would not be any lysosomes that will break down waste products, which keep the cell from dying rapidly.

Complete the following sentences to examine various components of the endomembrane system.

Information within the ____________ is transcribed into mRNA and transported outside the nuclear envelope.

Proteins, which are synthesized by ____________ , are then released into the ____________ , where they are further folded and modified.

The ____________ does not have attached ____________ and produces lipids, such as steroids.

Once proteins are folded and modified, transport vehicles called ____________ pinch off and surround them with membranes to be transported elsewhere.

The vesicles are moved to the ____________ where they are sorted and packaged.

Transport vehicles called ____________ carry the macromolecules to the ____________ where they fuse and release their contents to the outside environment.

ribosomes

Golgi apparatus

smooth endoplasmic reticulum

vesicles

plasma membrane

rough endoplasmic reticulum

nucleus

secretory vesicles

please fill in the blanks with the words given:

The ____________ Golgi apparatus is a series of membranous organelles that work together and communicate by means of transport ____________ vesicle(s).

These ____________ vesicle(s) can fuse readily with other organelles because they each contain membrane associated ____________ endoplasmic reticulum that enable communication.

For example, a protein that is synthesized is first transported to the ____________ endomembrane system, then moves to the ____________ endoplasmic reticulum via a ____________ Golgi apparatus.

This vesicle fuses readily with the ____________ proteins because the ____________ on the membrane target the ____________ on the ____________ 's membranes.

In this manner, endomembrane ____________ proteins are able to fuse readily with various organelles.

word choices:

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?

Question 8 options:

A)	They would be glycosylated in the Golgi apparatus.

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.

D)	They would be manufactured on free ribosomes in thecytoplasm.
