Lactobacillus Bulgaricus Probiotic - 3D microscopic view of healthy gut bacteria cells.  Lactobacillus bulgaricus is often found in greek yogurt and is considered one of the healthy gut bacteria that aids in digestion and promotes health.
Antimicrobial susceptibility testing in petri dish. Microbiologist check Antibiotic resistance of bacteria
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.

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.
