Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...
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 ...
A schematic of a polymer electrolyte membrane hydrogen-oxygen fuel cell is shown in Figure 1. Figure 1. Hydrogen-oxygen PEM fuel cell. Hydrogen molecules dissociatively adsorb at the anode and are ...
