This is from publication: Technical and didactic problems of virtual lab exercises in ...Enzyme kinetics is the study of the chemical reactions that are catalyzed by enzymes. In enzyme kinetics, the reaction rate is measured and the effects of varying the conditions of the reaction are investigated. Studying an enzyme's kinetics in this way can reveal the catalytic mechanism of this enzyme, its role in metabolism, how its activity is controlled, and how a drug or an agonist ...2. Temperature of reaction mixture. Increasing the temperature of the system usually speeds up chemical reactions. As the temperature increases, the reactant molecules move faster and with higher energy. As a result, they undergo reactions more frequently, thereby increasing the reaction rate.

Chemical and enzyme kinetics follow the same laws; however, enzyme kineticists should consider that in either relatively high or relatively low temperatures, enzymes may denaturize, where a sudden decrease of the occurring reaction rate is observed. Thus, the thermal stability of enzymes should be confirmed within a temperature range under the ...

S + E ⇌ ES → P + E. Two important terms within Michaelis-Menten kinetics are: Vmax – the maximum rate of the reaction, when all the enzyme’s active sites are saturated with substrate. Km (also known as the Michaelis constant) – the substrate concentration at which the reaction rate is 50% of the Vmax. Km is a measure of the …ENZYME KINETICS Enzyme Enzymes are proteins that act as catalysts of specific reactions. By providing an alternative reaction with a lower activation energy, they allow the reaction to proceed at a much higher rate. It is important to note that enzymes do not change the equilibria of a reaction; they can only increase the rate. Without the enzyme, the reaction would therefore still proceed in ...Conclusion Enzymes are very efficient catalysts for biochemical reactions.
