INTRODUCTION. Enzyme-dependent fluorescence recovery after photobleaching (ED-FRAP) has recently been described as a method of monitoring enzymatic activities in microsamples in vitro or cells using confocal microscopy techniques (Combs and Balaban, 2001).This approach relies on the transient photobleaching or photolysis of a fluorophore product of an enzymatic reaction and observing its ...Enzyme Kinetics. I.H. Segel, in Encyclopedia of Biological Chemistry (Second Edition), 2013 Abstract. Enzymes are protein catalysts that accelerate the rates at which reactions approach equilibrium. Enzyme kinetics is the branch of biochemistry that deals with a quantitative description of this process, mainly, how experimental variables affect reaction rates.4.3 Initial rates. Although Henri [ 3] derived the equation for the initial rate of an enzyme-catalysed reaction, he did not use it as the basis for a method of analysis. Instead, Michaelis and Menten [ 4] recognized that extrapolating the rate to zero time would overcome several problems: 1.Kinetics deal with the rate of a chemical reaction, that is, how fast it goes.
