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, PDB 2j0D, white background.
Cells in the body examined by endoscope
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.

Spike glycoprotein homotrimer, a main target for neutralization antibody, to bind its receptor, and mediate membrane fusion and virus entry. Surface model, white background.
Slice of natural crystal for patterns and textures use with high resolution.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
DNA A-T Pair
Biological protein and molecule, 3d rendering. 3D illustration.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
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
Abs Virus - 3d rendered image like colorized scanning electron micrograph. Scene showing virus (yellow)  emerging from infected cell.\nConcept of coronavirus that’s causing a global pandemic. Covid-19, Sars-cov-2 alpha, betta, gamma, delta, lambda variant, 2019-nCoV, Coronavirus.\nSEM, TEM, hologram view.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background
Liver Fluke Section under light microscope with white background
A GTP-bound G-alpha protein (blue) binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
Close-up shooting of a green agate stone mineral surface isolated on white background. Its a macro shot shows nature beautiful details with back lit. Agate is a kind of natural gemstone. Abstract pattern. Good for Wallpaper texture background. Turquoise, blue
