Air, like other fluids, moves from a region of higher pressure to a region of lower pressure. The flow of air into the lungs. requires that a pressure gradient between the atmosphere and the alveoli be established. This driving pressure. gradient is accomplished by the contraction of the inspiratory muscles.
Rabbit muscle phosphoglucomutase, drawn from PDB: 1JDY â. Phosphoglucomutase (EC 5.4.2.2) is an enzyme that transfers a phosphate group on an Î±-D-glucose monomer from the 1' to the 6' position in the forward direction or the 6' to the 1' position in the reverse direction.More precisely, it facilitates the interconversion of glucose 1-phosphate and glucose 6-phosphate.hosphoglucomutase also acts in the opposite fashion when blood glucose levels are high. In this case, phosphoglucomutase catalyzes the conversion of glucose 6-phosphate (which is easily generated from glucose by the action of hexokinase) to glucose 1-phosphate.
2. Insulin stimulates the liver to store glucose in the form of glycogen. A large fraction of glucose absorbed from the small intestine is immediately taken up by hepatocytes, which convert it into the storage polymer glycogen.he only mechanism by which cells can take up glucose is by facilitated diffusion through a family of hexose transporters. In many tissues-muscle being a prime example-the major transporter used for uptake of glucose (called GLUT4) is made available in the plasma membrane through the action of insulin.
