Question

Cells of the pancreas will incorporate radioactively labeled amino acids into proteins. This tagging of newly synthesized proteins enables a researcher to track their location. In this case, we are tacking an enzyme secreted by pancreatic cells. What is the most likely pathway

Answer 1

Answer:

Cells of the pancreas will incorporate radioactively labeled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track the location of these proteins in a cell. In this case, we are tracking an enzyme that is eventually secreted by pancreatic cells.

Answer 2

In this case we are tracking enzymes which will go through a series of packing and processing to be delivered to their respective targets. The sequence followed will be ER→Golgi→Vesicles that fuse with the plasma membrane.

Explanation:

1. First the radioactive proteins will be synthesized by the rough ER membrane.
2. The process of packing and processing will take place in the Golgi apparatus.
3. The final product (enzymes) will then be released through the vesicles by the process of exocytosis.
