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.
Glycogen is a high molecular mass polysaccharide that serves as a repository of glucose for use in times of metabolic need. Glycogen synthase (EC 2.4.1.11) catalyzes the addition of glucose monomers to the growing glycogen molecule through the formation of alpha-1,4-glycoside linkages (Pederson et al., 2004).2007) summarized the functions of muscle glycogen synthase and liver glycogen synthase, the key enzymes of glycogen synthesis, encoded by the GYS1 and GYS2 (138571) genes, respectively. The liver enzyme expression is restricted to the liver, whereas the muscle enzyme is ubiquitously expressed.
