Example Question #144 : High School Biology
Which of the following is not considered part of the eukaryotic endomembrane system?
Cell membrane
Endoplasmic reticulum
Golgi body
Mitochondria
Vesicle
Mitochondria
The endomembrane system is a collection of membranes making up a cell that are connected either physically or via transport using vesicles. One of its main functions is to package and "ship" things made in the cell to other places in the organism, such as hormones like insulin. In order to do this, different organelles with different functions are necessary, just like there are different people with different jobs who make sure a package is mailed to the proper place.
Example Question #145 : High School Biology
Where is ribosomal RNA formed?
Mitochondria
Rough endoplasmic reticulum
Nucleolus
Golgi apparatus
Smooth endoplasmic reticulum
Nucleolus
The nucleolus is a specialized region found within the nucleus. It is responsible for synthesizing ribosomal RNA (rRNA), while transcription of messenger RNA (mRNA) and transfer RNA (tRNA) occurs in parts of the nucleus other than the nucleolus.
