In recent years, the presence of bacteria in the body has been reported as the cause of various biological phenomena, and the subject of bacteria is often a hot topic. This image shows bacteria under a microscope. These images of bacteria can be used universally for both good and bad bacteria.\nThis image was not created by AI.
Calreticulin, a protein which binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the Golgi apparatus. 3d rendering.
Yeast cells - 3d rendered image SEM (scanning electron micrograph) view of cells of brewer's yeast (Saccharomyces cerevisiae).  It is used in the production of beer, wine and bread.
3D model of a protein molecule. Endothelial tyrosine kinase receptor, a marker of angiogenesis.
Abstract green and blue spheres arranged in lines.
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.

Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung.
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
The amyloid beta peptide (light blue) is a component of the amyloid precursor protein, which is bound to a cell membrane. The gamma secretase enzyme cuts the free form, that aggregates to amyloid plaques. Source: PDB entries 2beg, 1mwp
