Example Questions

Example Question #31 :Cell Biology

Which component of the Golgi apparatus is primarily responsible for "receiving" proteins to be packaged and modified?

Possible Answers:

Cisternae

Medial Golgi

Trans Golgi

Vacuoles

Cis Golgi

Correct answer:

Cis Golgi

Explanation:

cis Golgi is usually closely apposed to the endoplasmic reticulum, where proteins are synthesized by ribosomes. Once they have left the ribosome, the proteins are already close to the Golgi and are taken up by thecisside of the apparatus. Thetrans Golgi sends the newly packaged proteins out to their final destinations.

Example Question #31 :Cell Biology

Which component/suborganelle structure of the Golgi apparatus accepts vesicles from the rough endoplasmic reticulum containing nascent proteins to be processed through the Golgi apparatus?

Possible Answers:

Cis face

Trans Golgi stack

Lumen

Trans face

Medial Golgi stack

Correct answer:

Cis face

Explanation:

的cis face of the Golgi apparatus is the first part of the apparatus that faces the rough endoplasmic reticulum and interacts with recently synthesized proteins that need to be processed and packaged by the Golgi apparatus. The rest of the structures listed are indeed parts of the Golgi that the proteins must pass through during the course of processing, but the cis face is met first.
