Q138 / 180 · NEET 2015 (Phase 2) · Zoology

The function of the gap junction is to:

  • Correct answer
    A
    Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules
  • B
    Separate two cells from each other
  • C
    Stop substance from leaking across a tissue
  • D
    Performing cementing to keep neighbouring cell together

Solution

Gap junction: At place, the adjacent cells form ion-rich gap junctions for intercellular communication and chemical exchange. These junctions do not provide physical support but facilitates communication between two adjoining cells by protein bridges for rapid transfer of ions, small molecules and large molecules.

Hence, the correct answer is option: 'A'.
