Ubiquitin is a small regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. 3D cartoon and Gaussian surface models, white background.
Chemical formula of Progesterone
Molecular model of insulin hormone, 3D illustration. It is produced by pancreas and takes part in glucose and lipid metabolism
3D realistically coloured hexagonal shapes of connected spheres, background with copy space. Futuristic illustration design template for scientific presentation. Molecular business, science, teamwork concept.
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.
