This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins ... of ATP inside the cell. This diagram shows molecules moving from area ...

Scientists who model membrane structure and dynamics describe ... Thanks to membrane barriers and transport proteins, the cell can accumulate nutrients in higher concentrations than exist in ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

In a recent study published in Nature, researchers used cryo-electron microscopy (cryo-EM) to visualize the structure and dynamics of a membrane microdomain in yeast cells. They aimed to ...

Cells are microscopic building blocks of unicellular and multicellular living organisms. Animal, plant, fungal and bacterial cells are different in terms of structure but also have many similarities.

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.
