Proteins and lipids are modified into glycoproteins and glycolipids by which cell organelle?

Explanation

Proteins and lipids are modified into glycoproteins and glycolipids primarily by the Golgi complex (also known as the Golgi apparatus or Golgi body).The Golgi complex is involved in post-translational modification of proteins and lipids, including the addition of carbohydrate chains to proteins (glycoproteins) and lipids (glycolipids), which are important for various cellular functions, including cell-cell recognition and signaling. Rough endoplasmic reticulum (Option B) is involved in protein synthesis and initial protein folding, while smooth endoplasmic reticulum (Option C) plays a role in lipid metabolism and detoxification. Ribosomes and chromosomes (Option D) are not directly involved in the modification of proteins and lipids into glycoproteins and glycolipids.
