Caption: This graphic illustrates an intermediate step in the process that brings nutrients or other substances into cells. The membrane proteins are shown holding the nutrient in a small cavity within the cellular membrane. A Purdue team led by Jue Chen, an associate professor of biological sciences, captured an image of a key step that reveals interactions of the main proteins involved in the process.
