Question

Which is substitution of mitochondria in E. coli?

• A. Golgi body
• B. Mesosome
• C. Ribosome
• D. Glyoxysomes

Answer 1

The correct option is B Mesosome

Mesosomes are folded invaginations in the plasma membrane of bacteria. It is folded protuberances or membranous elaborations that occur irregularly at the inward side of the cell membrane of the prokaryotic organisms like certain cyanobacteria, nitrogen-fixing bacteria (e.g., Azotobacter), sporulating bacteria, etc.

The major function of mesosomes is to increase the surface area of the plasma membrane. This drastic increase in the surface area of the membrane mainly helps the cell to carry out cellular respiration more efficiently.

So, we can say it is a substitution of mitochondria in E. coli.
