ENZYMES ARE HIGHLY SPECIFIC Enzymes are highly specific both in the reaction catalyzed and in their choice of reactants, which are called substrales. An enzyme usually cata- lyzes a single chemical reaction or a set of closely related reactions. Side

This equation accounts for the kinetic data given in Figure 8-15.At very low substrate concentration, when [S] is much less than KM, V [s]Vmax/KMi that is, the rate is directly proportional to the substrate concentration At high substrate concentration, when [SI is much greater than KM, V=Vmax; that is, the rate is maximal, independent of substrate

Much of the catalytic power of enzymes comes from their bringing sub- strates together in favorable orientations in enzyme-substrate (ES)com- plexes. The substrates are bound to a specific region of the enzyme called the active site. Most enzymes are highly selective in their binding

process can occur spontaneously is that the entropy changes of chemical reactions are not readily measured. Furthermore, the criterion of sponta- neity given in equation 2 requires that both the entropy change of the surroundings and that of the system of interest be known. These difficul- ties are obviated by using different thermodynar function called the free energy, which is denoted by the symbol G (or F, in the older literature)

一、什么是生物传感器? 生物传感器(Biosensor)是指用固定化的 生物体成分或生物体本身作为敏感元件 的传感器,是一种将生物化学反应能转 换成电信号的分析测试装置
