This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: NEET 2018, Subject name: Physiology
Glucose is absorbed in intestine by? 
Select and explain. 
A. Secondary active transpo, B. Facilitated diffusion, C. Simple diffusion, D. Primary active transpo
A: Secondary active transpo
Answer: A: Secondary active transpo 
Explanation: 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
