Question

protein synthesis
protein synthesis occurs in which organelles? select all that apply.
golgi apparatus
smooth endoplasmic reticulum (er)
ribosome
nucleus
rough endoplasmic reticulum (er)

Explanation:

Ribosomes are the sites of protein synthesis, where amino - acids are assembled into proteins. The rough endoplasmic reticulum (ER) is studded with ribosomes and also participates in protein synthesis. The Golgi apparatus modifies, sorts, and packages proteins synthesized elsewhere, not the main site of synthesis. The smooth ER is involved in lipid synthesis and other functions, not protein synthesis. The nucleus contains DNA but is not the site of actual protein synthesis.

Answer:

C. Ribosome, E. Rough Endoplasmic Reticulum (ER)
