Question

The function of gap junction is to

• A. Cementing to keep neighbouring cells together
• B. Facilitate communication between adjoining cells by connecting their cytoplasms for rapid transfer of ions, small molecules and some large molecules
• C. Separate two cells from each other
• D. Stop substances from leaking across a tissue

Answer 1

Answer: (B)

Facilitate communication between adjoining cells by connecting their cytoplasms for rapid transfer of ions, small molecules and some large molecules

• Gap junctions can be defined as the specialized intercellular connection found between different animal cells.
• It directly connects the cytoplasm of two cells and allows the movement of different molecules, ions and electrical impulses through a regulated gate between cells.
  
• So, the correct answer is 'Facilitate communication between adjoining cells by connecting their cytoplasms for rapid transfer of ions, small molecules and some large molecules'.
• Option B is correct.
