Gap junctions permit intercellular movement of a variety of ions and small molecules.

Question

BlackTom AI · Accepted Answer

Consider the statement about gap junctions and intercellular movement. Gap junction channels connect adjacent cell membranes and allow direct cytoplasmic exchange between cells, enabling ions and small molecules to pass through.
Option 1: 'Flase' appears to be a misspelling of 'False.' Since gap junctions do permit movement of ions and small molecules, this option is incorrect due to factual inaccuracy and the typographical error.
Option 2: 'True' accurately reflects the biological function of gap junctions, which facilitate intercellular communication by permitting diffusion of ions, second messengers, and small metabolites between connected cells, thereby coordinating cellular activities across tissue.
A common misunderstanding might be thinking gap junctions only transmit large molecules or signals; in reality, the selective permeability favors small inorganic ions (like Na+, K+, Ca2+) and small signaling molecules (such as cyclic AMP), which underpins coordinated physiological responses.
In summary, the statement aligns with established physiology, whereas the alternative option is incorrect due to both a spelling error and a mismatch with the actual function of gap junctions.
