Add creativity and flexibility to your demonstrations of protein processes with this set of magnetic model pieces. Using the included magnets, you can model basic cell structure, cell size, ETC cellular respiration, ETC photosynthesis, nerve impluse, membrane transport, diffusion, endocytosis, exocytosis, and more. Begin by building a simple cell membrane using only phospholipids. From that point, proteins and sugars are added, increasing the complexity of the membrane. You can continue to increase the complexity by building organelles using the same pieces. This unique kit, developed by John MacLellan allows you to illustrate how the same molecules are used repeatedly in different biological processes.
