Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 3omv, white background
Particles, medical 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.

3D cartoon and Gaussian surface models, PDB 6p8e, white background
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
Biological protein and molecule, 3d rendering. 3D illustration.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
Bacterial cell or virus, 3d generated view from microscope.
