   Jul 17, 2024 · These junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another. Molecules that can pass between cells coupled by gap junctions include inorganic salts, sugars, amino acids, nucleotides, and vitamins but not large molecules such as proteins or nucleic acids.

   What is a gap junction?

   • To summarize, in early literature the term "gap junction" referred to the regular gap between membranes in vertebrates and non-vertebrates apparently bridged by "globules". The junction correlated with the cell's ability to directly couple with its neighbors through pores in their membranes.

   Jul 16, 2024 · Transistor - Semiconductor, Amplification, Switching: Shortly after his colleagues John Bardeen and Walter H. Brattain invented their point-contact device, Bell Labs physicist William B. Shockley recognized that these rectifying characteristics might also be used in making a junction transistor. In a 1949 paper Shockley explained the physical principles behind the operation of these junctions and showed how to use them in a three-layer—n-p-n or p-n-p—device that could act as a solid ...
