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.
Lily leaf c.s. under microscope
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.
Host cells with spores (mold) are inside wood under the microscope for education.

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.

Chloride channels conduct chloride anions across cell membranes, regulating the electrical excitation of skeletal muscles and the flow of salt and water across epithelial barriers. They also play an importante role in  regulation of pH, volume homeostasis, organic solute transport, cell migration, cell proliferation and differentiation.Genetic defects in Cl- channels underlie several familial muscle and kidney diseases.
