Draw a cell with 0.2mM glucose inside and 0.01mM glucose outside. Assume the extracellular sodium concentration is 150mM and the intracellular sodium concentration is 20mM. Use what you know about transport across membranes to propose a way that the cell can bring in more glucose when it needs to (i.e. When it uses some of the glucose to power cell processes, and has to bring in more glucose).
