Question : If they had instead performed this assay on muscle cells, which have high energy demands and primarily consist of actin and myosin filaments, where would you expect the labeled proteins to go during the chase?

-from the Golgi apparatus and the rough ER to the cytoplasm and the nucleus

-from the rough ER to the Golgi apparatus

-from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria

-from the cytoplasm to the Golgi apparatus

Answer:

-from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria

Explanation:

Proteins which have to be secreted, pass through the secretory pathway in the following order:

From the Rough Endoplasmic Reticulum (where they are synthesized) moves to Golgi transport vesicles to the Golgi cisternae and secretory or transport vesicles are formed which then move to the cell surface by passing through the cytoplasm and by exocytosis move outwards. Small transport vesicles bud off from the endoplasmic reticulum and join to form the Golgi reticulum.

Hence the correct answer is that the labeled proteins to go from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria during the chase.
