Which of the following is not a function of membranous extensions like vesicles and tubules?

Options

  1. ACell wall formation
  2. BIncrease the surface area of the plasma membrane
  3. CHelps in protein synthesis
  4. DHelps in respiration

Correct answer

C. Helps in protein synthesis

Step-by-step solution

A special membranous structure is the mesosome which is formed by the extensions of plasma membrane into the cell. These extensions are in the form of vesicles, tubules and lamellae. They help in cell wall formation, DNA replication and distribution to daughter cells. They also help in respiration, secretion processes, to increase the surface area of the plasma membrane and enzymatic content.
