<prompt> Glucose absorption from GIT occurs by:Simple diffusionFacilitated diffusionSecondary active transpoEndocytosis  <response>: Glucose enters all the cells by facilitated diffusion GLUTs. It enters the cells and is trapped within the cells, to be metabolized. In the case of GIT and kidney, where glucose movement is occurring across the cells for absorptionreabsorption, glucose movement from the lumen into the cells, across the apical membranes of cells, is occurring low-to-high concentration and hence is an example of secondary active transpo or co-transpo. The carrier is SGLT.
