Question

1. the endomembrane system includes various organelles that aid in the production of proteins. choose the correct order of major steps a cell goes through to synthesize and export proteins.

a protein is exported through the rough endoplasmic reticulum
b instructions are read to direct the assembly of proteins
c proteins are packed, sorted, and tagged for their final destination
d proteins are transported outside of the cell via exocytosis to where they are needed
a b c d
b a c d
b c a d
b a d c

Explanation:

First, genetic instructions (DNA) are read to direct protein - assembly (b). Then, the protein is exported through the rough endoplasmic reticulum (a) where initial modifications may occur. Next, proteins are packed, sorted, and tagged in the Golgi apparatus (c). Finally, proteins are transported outside of the cell via exocytosis (d).

Answer:

b, a, c, d
