How can glucose be transported against its concentration gradient without the direct expenditure of ATP in intestinal epithelial cells?Group of answer choices It uses simple diffusion It uses the Glut1 transporter It uses the Glucose ATPase It uses the Glucose/Na+ symporter None of the above. Due to the Second Law of Thermodynamics, molecules cannot be moved against their concentration gradient.
