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.
Glycolysis is the process by which energy is liberated from glucose. It occurs in the cytosol of the cell. It is an important energy provider for cells that lack mitochondria, the cell organelle in which aerobic metabolism occurs. Glycolysis also provides energy in situations when delivery of oxygen to the cell is delayed or impaired. (anaerobic glucose catabolism yielding 2 pyruvate and 2 ATP) Glycolysis involves a sequence of reactions that converts ____ to ____ with the concomitant production of ATP from ADP.
