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.
Pyruvate Kinase. I.U.B.: 2.7.1.40 ATP: pyruvate O2-phosphotransferase. Enzymatic Reaction (image will open in a new window). Pyruvate kinase catalyzes the reaction: Pyruvate kinase (PK) is a key enzyme in glycogen metabolism. Mammalian PK of different tissues are distinct, their characteristics being related to tissue metabolic requirements (Bigley et al. 1974; Boivin and Galand 1974). The enzyme has been well reviewed by Kayne (1973).
