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 a metabolic pathway that takes place in the cytosol of cells in all living organisms. This pathway can function with or without the presence of oxygen. In humans, aerobic conditions produce pyruvate and anaerobic conditions produce lactate.he reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called high-energy bonds are replaced by stronger bonds in the products. Respiration is one of the key ways a cell gains useful energy to fuel cellular activity.
