The cellular respiration (complete oxidation of fuels) can be divided into three stages Stage I All the fuel molecules are oxidized to generate a common two-carbon unit, acetyl-CoA. Stage II The acetyl-CoA is completely oxidized

1. Enzymes were among the first biological macromolecules to be studied chemically 1.1 Much of the early history of biochemistry is the history of enzyme research. 1.1.1 Biological catalysts were first recognized in studying animal food digestion and sugar fermentation with yeast (brewing and wine making)

Assay:化验,分析,测定。 Enzyme activity: unit() is defined as the amount of enzyme which convert 1 micromole (umol) of substrate to product(s) in 1 minute under specified conditions. Specific activity: enzyme activity expressed per unit mass of protein present. (units/mg)
