Which of the following modifies proteins and lipids by adding carbohydrates?
Correct answer: A. Golgi Apparatus
- A. Golgi Apparatus
- B. Polysome
- C. Plasma membrane
- D. None of these
Explanation
The Golgi apparatus is an organelle known for its role in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell. It adds carbohydrates to proteins and lipids, forming glycoproteins and glycolipids. The other options are incorrect: the polysome is involved in protein synthesis, not modification; the plasma membrane serves as a cell boundary, and 'None of these' is not applicable because the Golgi apparatus is the correct answer.
