The conjugation of proteins and lipids with carbohydrates is carried out in:
Correct answer: C. Golgi apparatus
- A. Smooth Endoplasmic Reticulum (SER)
- B. Rough Endoplasmic Reticulum (RER)
- C. Golgi apparatus
- D. Mitochondria
Explanation
The correct answer is the Golgi apparatus, which is crucial for processing, modifying, and packaging proteins and lipids. It adds carbohydrate groups to these molecules in a process called glycosylation, crucial for their final functional forms. The Smooth Endoplasmic Reticulum (SER) focuses on lipid synthesis and does not partake in glycosylation. The Rough Endoplasmic Reticulum (RER) is involved in the initial stages of protein synthesis but not in the addition of carbohydrates. Mitochondria are entirely unrelated to this process as they are dedicated to energy production.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
