Question

The function of a gap junction is to
A. Facilitate communication between adjoining cells by connecting the cytoplasm to rapidly transfer ions, small molecules, and some large molecules.
B. Separate two cells from each other.
C. Stop a substance from leaking across a tissue.
D. Performing is cementing to keep neighboring cells together.

Answer 1

Hint:
Before we proceed with the problem, we must know the definitions of Gap junction
Ions and small molecules can pass freely between cells thanks to gap junctions, which are groups of intercellular channels. Nearly all cells in solid tissues are connected by gap junctions, which were first discovered as low-resistance ion channels joining excitable cells (nerve and muscle). Communication junctions, macula communicators, and nexuses are other names for gap junctions.

Complete step by step answer:
There is still much to learn about Gap junction. Facilitate communication between adjoining cells by connecting the cytoplasm for the rapid transfer of ions, small molecules, and some large molecules. The function of gap junction is to facilitate communication between adjoining cells by connecting the cytoplasm to rapidly transfer ions, small molecules, and some large molecules.
Connexons from neighbouring cells are opposed to creating gap junctions; each connexon is made up of six connexin proteins.
Due to the fact that gap junctions exist between every cell that touches another cell directly, the vast majority of cells in the body include them. Red blood cells and sperm cells are two exceptions because they travel and don't typically come in contact with other cells closely.

Option ‘A’ is correct

Note:
Gap junctions are membrane channels that facilitate the flow of ions and tiny metabolites from one cell to another. Gap junctions are crucial for impulse conduction in the heart. The connexins are a multigene family that has been implicated in the last ten years' worth of research in explaining how gap junctions are encoded.
