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.

A molecular model of the flavonoid Quercetin. An antioxidant and anti-inflamatory, it is used as a nutritional suplement. It is commonly found in many fruits and vegetables and is a significant chemical component of tea. Isolated on white.

Science background with molecule or atom

Molecular model of tyrosine, one of 20 required amino acid to form proteins.

Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background

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.
