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 ...

which evolutionarily diverged approximately 4 billion years ago and exhibit significant biological differences in cell membrane lipids, genetic information, and other biochemical characteristics.

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 ...

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

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 ...
