13. Insulin secreted by Beta cells of pancreas, how does insuline enter bloodstream?

a. RER
b. SER
c. Golgi app
d. liver
e. a,b, and c

Weird question, i think it'd be something like RER and golgi app since secreted proteins follow this pathway. produced in RER, transported to golgi and then vesicles where it gets secreted through PM.

SER is site of hormone formation.

SER is site of hormone formation.

Insulin is produced by the RER not SER.

 

[Dencology]

RER is responsible for protein synthesis and Insuline is a protein. so it would make sense that would be produced by SER. but how does it enter the blood?

 

[lhtran07]

Golgi Apparatus because previously synthesized insulin are stored in secretory vesicles.

Remember--Wikipedia is your friend:
The primary function of the Golgi apparatus is to process and package the macromolecules such as proteins and lipids that are synthesized by the cell. It is particularly important in the processing of proteins for secretion.

look at it this way... the question didnt ask you where does insulin synthesis occur. it asks how does it get in the blood, so golgi for sure.

Where did you find this type of question? I thought this question is very good source to practice DAT bio. Would you mind if you let me know? 🙂
