Webb11 juni 2016 · These gap junctions are transmembrane channels that allow for the diffusion of small molecules between the neighbouring cells (Fig 13-2A). In general, ions—small organic molecules, low-molecular-weight precursors of proteins and nucleic acids—and small signalling molecules can pass through gap junctions whereas proteins … WebbMost channels are for ions like Na+ or water, which are very small. So the channel can be specific by having a very small channel that only allows the right size ion with correct …

WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane ( Figure 3.8) made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group. WebbWhat’s found inside a cell. An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little …
