Question

The function of respiration in a bacterial cell is taken up by a structure formed from

• A. cell wall
• B. plasma membrane
• C. cytoplasm
• D. capsule

Answer 1

The correct option is B plasma membrane

Mesosomes are infoldings of the plasma membrane found in bacterial cells. They help in respiration as they have enzymes needed for cellular respiration. Besides this, they also help in secretion processes and increase the surface area of the plasma membrane.
They also help in cell wall formation, DNA replication, and distribution to daughter cells.
