This tutorial will help you to understand how a molecule can be transported across a membrane against a concentration gradient. Cellular membranes function to keep the internal environment of the cell distinct from the external environment. Concentrations of many molecules differ across cellular membranes. This animation shows the function of the sodium potassium pump.
