Granular endoplasmic reticulum is mainly concerned with:
Correct answer: B. Peptide bond formation
- A. Proteolysis
- B. Peptide bond formation
- C. Glycosidic bond formation
- D. Fatty acid and cholesterol synthesis
Explanation
Granular ER is called so because it has ribosomes attached to its surface. These ribosomes are responsible for protein synthesis. Proteins contain polypeptide chains synthesized by peptide bond formation between amino acids.

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.
