Sculpted as a membrane cross section, this hydrogen potassium ATPase proton pump shows how a stomach cell pushes acid across its wall. Twisted helix ropes thread straight through a slab of lipid bilayer, with the tails of each lipid drawn as wavy strands between rounded heads. A knobbly beta subunit caps the top while the bulky alpha domains hang below the membrane. Its rough, bead-like surface reads clearly from any angle, making it a striking teaching piece for a cell biology classroom, a bioelectricity talk or a science lover's shelf.
