Glucose is absorbed in intestine by?: (A) Secondary active transpo, (B) Facilitated diffusion, (C) Simple diffusion, (D) Primary active transpo
Answer is A. In all cells: Glucose enters by (along conc. Gradient) facilitated diffusion GLUT, EXCEPT: GIT & kidney | Glucose has to enter against concentration gradient & cross the apical & basolateral cell surfaces to get absorbed into the bloodstream. The transpoer facilitating glucose absorption into the intestinal cells: SGLT secondary active transpo. Glucose exits from the cell to the bloodstream GLUT -2 (facilitated diffusion) Ans 1>2
