2. Describe the methods that cells used to transport glucose into cells, and briefly discuss the biochemical reaction that ensures that glucose remains within the cell.

Glucose is not absorbed directly by the cells. There are mechanisms that transport glucose into cells. The glucose transporter facilitates the transportation of glucose into the cells through the cell membrane (Bogan, 2012). The glucose moves from its region of high concentration outside the cell to a region of low concentration in the cell. Another method is active transport. The glucose transport protein relies on the concentration gradient that the cell has created during it glucose uptake. The glucose uptake depends on the glucose gradient from the body into the body cells.

Most of the body tissues contain a hydrolytic enzyme known as glucose-6-phosphatase that enables glucose to leave an organ. Muscle phosphorylase regulates the energy in a cell. The glucose-6-phosphatase absence in muscle tissues ensures that glucose-6-phosphate remains within the cell. It ensures that the glycogen remains trapped within the cell. High concentrations of AMP activate muscle phosphorylase. AMP binds and stabilizes phosphorylase b in the active state. The process thus, ensures that glucose remains within the cell.
