Why is it important to move glucose away from the basal membrane?
Homework Answers
Glucose is absorbed in the intestine using secondary active transport ( Na- GLUT transporter). For this transport energy is used. In side the intestinal cells , at basel membrane cell has another glucose transporter GLUT 2 which transport glucose by a process of facilitated diffusion. Facilitated diffusion is a type of diffusion where molecules are transported in either direction based on concentration gradient by mediating a protein , this protein facilitate the transport of glucose . So once a glucose molecule transported through this GLUT 2 , can come again out side the cell by using this transporter . This situation is prevented by moving away glucose from basal membrane or by rapid phosphorylation of glucose in side the cell.

Shown in the figure is a sketch of gut epithelial cells. The cells move glucose from the lumen of the gut across thei apical surface and into the cell, and then into the extracellular fluid/blood supply via their basal surface. Using the information in the figure, what type of transporter could be used to move glucose from: 1. The lumen into the cell (and if it requires energy, what is the energy source?). 2. The cell into the extracellular fluid...

As a rock is worn down, the pieces that are produced will move away from the source. Thinking just about just the minerals in Bowen's Reaction Series, how should those minerals be distributed going from a location close to the mineral source to a location far away from the mineral source? Think about the silicate classes and their relative strength or resistance to breaking down (not hardness). Another way to think about is like this; at what distance would olivine...
