Countertransport definition biology

WebAntiport or Counter-transport means that 2 different molecules or ions are being transported at the same time but opposite directions. One of the species is allowed to flow from high concentration to a lower concentration (often Sodium) while the other species is transported simultaneously to the other side. Examples: WebCotransport (Symport and Antiport) How can a molecule 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.
