what is the most likely endomembrane system pathway taken by a newly synthesized protein that will be secreted by a cell?
rough endoplasmic reticulum → golgi apparatus → vesicles that fuse with plasma membrane
golgi apparatus → rough endoplasmic reticulum → lysosome
rough endoplasmic reticulum → lysosomes → vesicles that fuse with plasma membrane
rough endoplasmic reticulum → golgi apparatus→ nucleus

Explanation:

• Rough endoplasmic reticulum: It is the site where proteins are synthesized.
• Golgi apparatus: It modifies, sorts, and packages proteins.
• Vesicles that fuse with plasma membrane: These vesicles carry the processed proteins to the cell membrane for secretion.

Lysosomes are involved in digestion, not secretion. The nucleus is not part of the secretion pathway for proteins.

Answer:

rough endoplasmic reticulum → Golgi apparatus → vesicles that fuse with plasma membrane
