A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.

Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
