Cell Junctions and Cell Signalling Pathways · Zoology

Gap junctions allow direct communication between cells by permitting the passage of:

  1. Large proteins and folded enzymes
  2. DNA fragments carrying genetic code
  3. Ions and small metabolites
  4. Hormones secreted into the bloodstream
Show answer and explanation

Correct answer: Ions and small metabolites

Gap junctions consist of connexon channels that allow ions and small molecules to pass directly between neighboring cells. This enables rapid cell-to-cell communication.
