Question

Which of these is not part of the endomembrane system of the cell?

• A. Mitochondria
• B. Endoplasmic reticulum
• C. Lysosomes
• D. Golgi complex

Answer 1

The correct option is A Mitochondria

The endomembrane system includes lysosomes, Golgi apparatus, nuclear envelope, ER and vesicles. The plasma membrane is also a part of the endomembrane system of the cell. Mitochondria are not a part of the endomembrane system because it is not directly involved in either receiving or forming the vesicles of the system. It performs the cellular respiration and is not involved in the transport and sorting of the molecules.

Hence, the correct answer is 'Mitochondria'.
