Question

15.
Insulin is a protein that is produced by certain pancreatic cells and secreted into the
bloodstream. (This is true.) Which of the following choices best describes the route
of insulin from its production to its exit from the cell?
Select an answer
A rough ER, transport vesicles, cell membrane
B rough ER, transport vesicles, Golgi apparatus, transport vesicles, cell membrane
C rough ER. Lysosomes, transport vesicles, cell membrane
D rough ER, Golgi apparatus, smooth ER, cell membrane​

Answer 1

Answer:

B rough ER , transport vesicles, Golgi apparatus, transport vesicles ,cell membrane.

Answer 2

• The pathway where insulin, a protein, is passed through an endoplasmic reticulum is a secretory pathway.
• The endoplasmic reticulum goes through the transport vesicle, which further goes down the Golgi apparatus.
• Then the final transport goes through lysosomes and finally passes through the plasma cell membrane.
• The Golgi apparatus is processing proteins that are made in the endoplasmic reticulum.
• This pathway is the secretory pathway.

Hence, the correct answer is rough ER, transport vesicles, Golgi apparatus, transport vesicles, and the cell membrane.
