Question

To get from intestines to blood, glucose has to be absorbed through intestinal epithelium. The reason why glucose does not enter into blood between intestinal cells is that they are sealed by _________ Glucose enters the intestinal epithelium on the apical side through If this transporter is defective blood glucose level measured after the meal would be ________. This condition is called glucose galactose malabsorption syndrome Glucose will leave intestinal cells. After it travels in blood, glucose enters the neurons in the brain through ______. The reason the brain is a "privileged organ when it comes to glucose delivery is because GLUT 3 has higher/lower cm affinity than other uniporters such as ______ or _______. The transport by uniporters uses does not use energy in the form of ATP. Glucose is flowing to or out of cells down with the gradient. Other glucose transporters such as Na^+ glucose symporter or SGLT1 use to bring glucose in. Some transporters do and tome don't use energy from ATP to do their job List 3 specific examples of transport proteins that transport molecules across the membrane without ATP hydrolysis.
