Glucose absorption from the gut occurs by:

A
Simple diffusion
B
Facilitated diffusion
C
Primary active transpo
D
Secondary active transpo
High-Yield Explanation
Glucose absorption from the gut occurs as co-transpo (secondary active transpo) with Na+ transpoer is SGLT-1 (sodium-glucose transpoer). SGLT-1 is a sympoer located on the luminal brush border of the enterocytes; it transpos 2 Na+ for every molecule of monosaccharide (glucose/galactose). Glucose moves across the basolateral membrane into the blood by passive transpo or facilitated diffusion GLUT-2 transpoer.
