Question

Which of the following is NOT a fate of a protein that is produced by the rough ER?

It functions inside of an organelle that is a member of the endomembrane system.

It functions in the cytoskeleton as a tubulin component of microtubules.

Is is secreted from the cell similar to how the protein called insulin is secreted from pancreatic cells.

It functions as a glycoprotein in the membranes of the golgi apparatus.

Answer 1

Answer:Is is secreted from the cell similar to how the protein called insulin is secreted from pancreatic cells.

Step-by-step explanation:

Answer 2

The second statement is incorrect.

Step-by-step explanation:

The proteins generated in the rough endoplasmic reticulum can be sorted to the cell membrane, Golgi apparatus, exterior to the cell, and lysosome.

As a component of microtubules tubulin is found in cytoplasm and these proteins of cytoplasm originate due to the translation process undergone by the cytoplasmic ribosomes, not by the ribosomes present on the rough endoplasmic reticulum. Thus, these proteins are not a component of endomembrane system.
