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.

The enzyme ADH from this case requires the co-factor Nicotinamide Adenine Dinucleotide, NAD +, in order to function. 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.Enzyme kinetics is the study of the chemical reactions that are catalyzed by enzymes.
