Oral rehydration therapy takes advantage of which transporter in GIT -: (A) Na Glucose co transport, (B) K glucose co transport, (C) Na calcium co transport, (D) Na channel
Answer is A. Ans. is 'a' i.e., Na Glucose co transport * Oral rehydration is possible if glucose is added with salt. It capitalizes on the intactness of glucose coupled Na+ absorption (Na glucose co transport), even when other mechanisms have failed or when intestinal secretion is excessive, because the secreted fluid lacks glucose and cannot be reabsorbed.
