Labster enzyme kinetics.
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 branch of biochemistry that deals with a quantitative description of this process, mainly, how experimental variables affect reaction rates. The variables that are studied include the concentrations of the enzymes, substrates (reactants), products, inhibitors, activators, the pH, temperature, and ionic strength.Enzyme inhibition. Enzyme inhibitors are molecules that decrease the activity of enzymes, and knowledge about inhibitors can, for example, be used in developing drugs or in the study of biochemical pathways, because inhibitors provide a way to interfere with these pathways.Enzyme inhibitors can be either irreversible or reversible; irreversible inhibitors decrease enzymatic activity by ...
