A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.

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.
Freshwater Closterium algae (unicellular charophyte green algae) - optical microscope x200 magnification
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.

Candida albicans grown on chromogenic agar plates. Candida albicans, a fungus naturally present in small quantities on the body, inhabits areas such as the mouth, skin, and intestines. When the balance with healthy bacteria is disrupted, Candida can lead to infections like thrush and vaginal yeast infections. These infections are frequent and typically addressed with antifungal medications.

Antimicrobial susceptibility testing in petri dish. Microbiologist check Antibiotic resistance of bacteria
Double zones can be seen around 3 antibiotic disks. This is a clear sign of more than one bacterium being present. To measure antibiotic susceptibility for each bacterium it will be necessary to isolate E. coli and Klebsiella on separate agar plates.
