Question 1
Which of the following organelles manufactures lipids and proteins?
- Endoplasmic reticulum
- Mitochondria
- Golgi apparatus
- Nucleus
- Lysosomes
Explanation: The endoplasmic reticulum is an organelle that manufactures proteins, steroid molecules, cholesterol, and other lipids. The rough endoplasmic reticulum is embedded with ribosomes to allow polypeptides to be translated into the interior of the organelle. The smooth endoplasmic reticulum is responsible for lipid synthesis and degradation of toxins.
