| Abstract: | The uptake of leucine through the tegument of Cotugnia digonopora, a cestode found in the fowl intestine, occurs by a process of active transport. The Kt of transport is 0.87 mM and the Vmax is 0.223 μmol/min/g. Uptake of the amino acid is competitively inhibited by valine (Kt = 1.30 mM). Potassium cyanide and 2,4-dinitrophenol do not completely block the entry of leucine into the parasite. |
