Expert-verified. 100% (2 ratings)The Michaelis-Menten equation not only quantified the kinetics of enzymatic reactions but also provided a practical means for characterizing an enzyme in terms of k cat and K M.A high k cat and a low K M, or a high k cat /K M ratio, are indicators for an enzyme's effectiveness. In 1934, Lineweaver and Burk showed how to rearrange the Michaelis-Menten equation to facilitate determination of K M ...In this enzyme kinetics case, at a specific substrate concentration, a master mix, containing NAD +, N A D plus ethanol, and buffer, can be prepared. The buffer keeps the pH of the reaction mixture stable. When the enzyme is added, the reaction starts, and the enzyme is therefore not included in the master mix.LabsterEnzyme Kinetics.

This co-factor takes up a hydride ion (H -) from the ethanol, leading to the formation of an acetaldehyde. NAD + is reduced to NADH and thereby works as an electron acceptor (see figure 1). NAD + is derived from the vitamin niacin.Virtual and experimental lab courses - from classic till new teacher tools are science education - looking for new creative to develop insert experimental courses, share your own experiences and discuss wherewith experimental courses may develop from step-by-step instructed (teacher driven) classes the lessons from superior lerning results.LabsterADH.
