Question

which organelle is primarily involved in the synthesis of lipids?
ribosome
golgi apparatus
smooth endoplasmic reticulum
rough endoplasmic reticulum

Explanation:

To determine the organelle for lipid synthesis, recall: Ribosomes make proteins. Golgi apparatus modifies/sorts proteins/lipids. Rough ER has ribosomes for protein synthesis. Smooth ER (no ribosomes) is key for lipid (e.g., phospholipids, steroids) synthesis.

Answer:

C. Smooth endoplasmic reticulum
