Internal structure of an animal cell, 3d rendering. Section view. Computer digital drawing.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism.

A new antibiotic (zosurabalpin, red) traps lipopolysaccharide (orange) in the intermembrane transporter of the Gram-negative bacterium Acinetobacter baylyi
Photomicrograph of newly hatched freshwater leech. Note multiple eyes at head and second attachment sucker at tail. Body length approx. 3 mm. Live specimen. Wet mount, 5X objective, transmitted brightfield illumination.
amazing inhabitants of the microworld under a microscope
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.
Hand of scientist or doctor showing a microbiological culture Petri dish with bacteria where an antibiotic resistance test has been carried out
Microscopic image of dog stomach cardiac region
Paramecium are widespread in freshwater, brackish, and marine environments and are often abundant in stagnant basins and ponds.
Tetis of Fish T.S. under light microscope with white background
Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome.
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
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.
