Question

The function of mesosome in prokaryotes is

• A. Aerobic respiration
• B. Cell wall formation
• C. Both (A) and (B)
• D. Nitrogen fixation

Answer 1

The correct option is C

Both (A) and (B)

The correct option is C.
Explanation for Correct option:

1. Mesosomes are extensions of the cell membrane that are present in the cytoplasm as infolding and function to increase surface area in cyanobacteria, a kind of photosynthetic prokaryote.
2. Mesosomes are involved in synthesis of the cell membrane,DNA replication and control the division of duplicated bacterial chromosomes between the two daughter cells.
3. Additionally, they increase the surface area for aerobic respiration and carry the enzymes necessary for it.

Final answer: The function of mesosome in prokaryotes is aerobic respiration and cell wall formation.
