Question

Mesosome helps in all, except

• A. Cell wall formation
• B. Respiration and secretion process
• C. Nucleotide synthesis
• D. Increasing the surface area of plasma membrane

Answer 1

Answer: (C)

Nucleotide synthesis

Mesosomes are the invaginations of plasma membrane in bacteria. Mesosomes perform various functions such as:

• Various respiratory enzymes are present in Mesosomes. Thus, mesosomes help in cellular respiration.
• The folded invaginations increase the surface area of plasma membrane.
• They also help in cell wall formation.
• They secrete various enzymes such as dehydrogenase and various components of electron transport chain.

Hence, mesosomes do not help in nucleotide synthesis.

So, the correct answer is 'Nucleotide synthesis'.
