The triose phosphate translocator is an integral membrane protein found in the outer membrane of chloroplasts. It exports triose phosphate (Dihydroxyacetone phosphate) in exchange for inorganic phosphate and is therefore classified as an antiporter. This protein is responsible for exporting all the carbohydrate produced in photosynthesis by plants and therefore most of the carbon in food that one eats has been transported by the triose phosphate translocator.[1]
