SGLT-2', 'role': 'user'}, {'content': "Answer: B \nExplanation: Ans. is 'b' i.e., GLUT-4 * Glucose is transported into the cells by two mechanismsi) Facilitated diffusion By glucose transporters (GLUT)ii) Secondary active transportBy sodium dependent glucose transporter (SGLT)* Insulin increases glucose uptake by increasing the GLUT4 on the cell membrane. Thus, insulin promotes facilitated diffusion i.e. diffusion along concentration gradient (not against concentration gradient). So, option b is incorrect.", 'role': 'assistant'}]
