Nuclear fusion reaction generating energy and light. Digital illustration.
A molecular model of Amyloid protein fibrils. Formed when mis-folded proteins self-assemble into fibrous sheet structures, they are found in the brains of sufferers of Alzheimer's disease and may be implicated in causing the disease.
Dna structure on science background. 3d illustration
Cells in the body examined by endoscope
Molecular model of insulin hormone, 3D illustration. It is produced by pancreas and takes part in glucose and lipid metabolism
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
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.
Open capsule or pill with molecular structure. Nanotechnology concept

3d rendering of transparent molecule shape on green color background.
The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
Calcidiol molecule, also called calcifediol, major circulating metabolite of vitamin D3 produced in liver, 3D illustration
3d render of abstract connection background
Folic acid, folate molecule. It is known as vitamin B9. Molecular model. 3D rendering. Illustration
Dna structure digital concept
Spirogyra sp. green algae under microscopic view - Chlorophyta, Green algae
Molecular model of Adenosine triphosphate,  or Adenosine-5'-triphosphate (ATP)
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
Open capsule or pill with molecular structure. Nanotechnology concept
Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that dimerizes. Red dots are phosphorylated tyrosines. The signal transduction continues through GRB2/SOS, Ras,  Raf/MEK and ERK, that will activate many processes in the cell.
