Question

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

Explanation:

Ribosomes are the sites of protein synthesis. The rough endoplasmic reticulum has ribosomes attached to its surface and is also involved in protein - synthesis processes. The nucleus contains DNA which codes for proteins but is not the site of actual protein synthesis. The smooth endoplasmic reticulum is mainly involved in lipid synthesis and detoxification, and the Golgi apparatus modifies, sorts, and packages proteins but is not a site of synthesis.

Answer:

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