monitta

The correct option is b. "IEC Na+/glucose symporters are found only in the plasma membrane (PM) facing the basal extracellular fluid"

Explanation:

The glucose in the intestine is a product of digestion and needs to be absorbed into the blood so it can be transported to where needed. Glucose moves out of the IEC with the combined action of sodium ions. The sodium-glucose symporter opens and allows for this pair to move out only when one of each is attached to the symporter. The movement of glucose is regulated in this way.
