Question

Why are mitochondria not part of the endomembrane system?

Answer 1

Endomembrane system:

1. Mitochondria are not there in the endomembrane system because the functions of mitochondria are not coordinated with the functions of the Golgi apparatus, endoplasmic reticulum, and lysosomes.
2. A eukaryotic cell's endomembrane system is made up of several membranes that are suspended in the cytoplasm.
3. Organelles, or functional and structural compartments, are separated from one another by these membranes.
4. The nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes, and plasma (cell) membrane are among the organelles of the endomembrane system in eukaryotes.
5. Formerly autonomous bacteria, mitochondria, and plastids now play crucial roles in the eukaryotic cells of plants and animals, respectively.
6. Therefore, they have their own systems of membrane barriers protecting them from the cytoplasmic environment outside.
