Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the ...

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 ...

The water concentration can be thought of as the proportion of a solution that is water. Solutions with a high concentration of solute molecules, such as sugars or salts, have a low concentration ...

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 ...

The Geertsma group is interested in understanding the molecular principles underlying transepithelial solute transport, with a focus on SLC26 family transporters. In this project, we aim to unravel ...

Most drugs target membrane proteins, accessible on the surface of cells, to alter the transport of ions and molecules and the transduction of cellular signals. The Diver lab explores the biological ...
