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.
Muscles also have big reserves of a complex carbohydrates called glycogen. Glycogen is a chain of glucose molecules. A cell splits glycogen into glucose. Then the cell uses anaerobic metabolism (anaerobic means without oxygen) to make ATP and a byproduct called lactic acid from the glucose.About 12 chemical reactions take place to make ATP under this process, so it supplies ATP at a slower rate than the phosphagen system.uscles also have big reserves of a complex carbohydrates called glycogen.
