What organelle manufactures proteins?

The Rough ER produces secretory proteins. Their pathway starts in the Rough ER, then the Golgi Apparatus and they are then packaged and transported outside the cell. Secretory proteins are made on bound ribosomes(ribosomes that don't float freely in the cytoplasm)... hope that helped


Question 5 text A secretory protein that exits from the ER within a vesicle will head directly to the?

A secretory protein that exits from the ER within a vesicle will head directly to the Golgi apparatus. It is an organelle that can be found in eukaryotic cells. It packages the proteins inside the cell before they are sent out to where they should be.


Secretory vesicles pinch off from what?

smooth er


What Sorts and ships secretory proteins?

The Golgi Apparatus modifies and packages proteins.


What structure tranports proteins?

Vacuole or vesicles are used to transport proteins and other molecules out of cells. These secretory vesicles are actually a part of Golgi bodies. After synthesis, protein undergoes modifications in ER and Golgi, where it packaged in those vesicles.


Where does synthesis of membrane proteins and secretory proteins happen?

Synthesis of proteins occurs in the Rough Endoplasmic Reticulum.


What is the function of the free ribosomes?

Free ribosomes, present in the cytoplasm, make proteins that remain in the cytosol, cytosolic proteins. Whereas membrane bound ribosomes (on Rough ER) make membrane proteins and secretory proteins etc. Hope this helps.

When the Golgi complex finish where do the proteins go?

The ER and Golgi complex serves a place for protein maturation. Polypeptide chain after synthesis undergoes folding events and post translation modification such as acylation, glycoscylation. Golgi vesicles secrete the protein to extracellular space if the proteins is a secretory proteins. It all depends on the destination signal in the proteins.


Is the endoplasmic reticulum an organelle?

Yes, the rough endoplasmic reticulum produces secretory proteins also known as enzymes. Secretory proteins means that these proteins are made for secretion or delivery outside the cell and into the body.
