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 ...
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 ...
Researchers meticulously examined the gametogenesis of budding yeast, a process involving meiosis and spore formation, using live imaging techniques. Their findings revealed that during sporulation, ...
(1) Most QWERTY computer keyboards use a single rubber-like membrane underneath the keys that makes contact with a circuit board when the key is fully depressed. Also called a "dome switch ...
Delivery to the sides of the cell is well understood ... that most of their bulk resides within or outside of the plasma membrane and not inside the cell—de Caestecker hypothesized that proteins ...
Reaction engineering principles are employed to develop a one-dimensional differential PEM fuel cell suitable for elucidating the dynamic performance of PEM cells under well-defined conditions.
