Lipids in cell membranes regulate the activity of a cancer-linked protein, cell biologists at RIKEN have discovered. This ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

All cell types ? Fluid enclosed by the cell membrane, containing organelles and ribosomes Location of many chemical reactions All cell types Mitochondria?-shaped structures found in ? Location ...

Location of reactions in anaerobic respiration ... used in chemical reactions such as photosynthesis and respiration. Cell membrane Allows gases and water to diffuse freely into and out of ...

Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

Physicists from the Universities of Bayreuth and Grenoble have discovered a new mechanism of cell mobility. Their findings ...

“This work challenges a major assumption of cell biology by showing that the plasma membrane, the flexible bilayer that surrounds the cell, can have drastically different phospholipid ...

Cell membrane proteins hide secret gateways that can be used to modify cell behavior. This has been demonstrated in a study led by the Hospital del Mar Research Institute and published in Nature ...

Aquaporins are proteins that rapidly transport water across cell membranes while excluding salt. They are critical for maintaining the right balance of water inside and outside cells and for ...
