The 2 in front of the oxygen gas and the 2 in front of the water vapor are called the reaction coefficients. They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic â two-atom â element) are the reactants, while carbon dioxide and water are the products.
Pyrophosphatase (or inorganic pyrophosphatase) is an enzyme (EC 3.6.1.1) that catalyzes the conversion of one molecule of pyrophosphate to two phosphate ions.he functionality of this enzyme plays a critical role in lipid metabolism (including lipid synthesis and degradation), calcium absorption and bone formation, and DNA synthesis, as well as other biochemical transformations.
The concentration of Fructose-2,6-bisphosphate is lowered so glycolysis is inhibited. When PFK-2/F-2,6-bisphosphatase is phosphorylated (P*) by Protein kinase A in muscle, PFK-2 is activated and F-2,6-bisphosphatase is inhibited. The concentration of Fructose-2,6-bisphosphate is raised so glycolysis is activated.P and P* are two different sites on the PFK-2/F-2,6-bisphosphatase enzyme complex. The addition of P inhibits PFK-2 in liver but the addition of P* activates PFK-2 in muscle.I cannot explain the mechanism of activation of PFK-2 and glycolysis by insulin in muscle but it is the major control point. and P* are two different sites on the PFK-2/F-2,6-bisphosphatase enzyme complex. The addition of P inhibits PFK-2 in liver but the addition of P* activates PFK-2 in muscle.
