The Golgi complex plays a major role
Correct answer: B. in post translational modification of proteins and glycosylation of lipids
- A. as energy transferring organelles
- B. in post translational modification of proteins and glycosylation of lipids
- C. in trapping the light and transforming it nto chemical energy
- D. in digesting proteins and carbohydrates.
Explanation
Post translational modification (PTM) is a step in protein biosynthesis. Proteins are synthesized in ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM, such as folding, cutting, and other processes, before becoming the mature protein product. Proteins synthesized by the rough endoplasmic reticulum and lipids synthesized by smooth endoplasmic reticulum reach the cisternae of the Golgi apparatus. Here, they combine with carbohydrates to form glycoproteins and glycolipids. This process is called glycosylation. A.Golgi complex doesnot transfer energy. C.This is the role of chlorophyll present in chloroplast. D.Intracellular digestion is the role of lysosomes.

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.
