Oral rehydration therapy takes advantage of which transporter in GIT -
Na Glucose co transport
K glucose co transport
Na calcium co transport
Na channel
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.
