Question

Quizplus · Accepted Answer

The sodium glucose symporter (SGLT1) is responsible for the absorption of glucose from the lumen of the small intestine into the epithelial cells. This process is coupled with the import of two sodium ions into the cell, which creates a favorable gradient for glucose transport. The GLUT carrier protein is responsible for transporting glucose out of the epithelial cells and into the bloodstream. The glucose pump and sodium channel are not involved in glucose absorption in the small intestine.
