Alpha-helices from syntaxin and synaptobrevin open these structures by "zippering." One of these structures is formed when LDL binds to AP2. Botulism and tetanus work by preventing these structures from being opened. A protein found on these structures consists of three light chains and three heavy chains in a triskelion shape. That protein forms soccer ball-shaped (*) cages around these structures. These structures are opened by SNARE proteins. When going between the Golgi apparatus and the endoplasmic reticulum, they

That protein forms soccer ball-shaped (*) cages around these structures. These structures are opened by SNARE proteins. When going between the Golgi apparatus and the endoplasmic reticulum, they can be coated with COPI or COPII. They form from clathrin-coated pits in endocytosis. Large ones used for storage are called vacuoles. For 10 points, name these bubble-like structures that transport molecules within and between cells.
