In this study, the enzyme alcohol dehydrogenase (ADH) is used to catalyze the conversion of ethanol (the substrate) to acetaldehyde (the product). Eight kinetic trials were carried out in a pH 9.0 buffer; only the concentration of ethanol was varied from one trial to the next. The reaction was followed spectrophotometrically, although in an ...Terms in this set (21) Enzymes. Proteins that speeds up the rate of a chemical reaction in a living organism. A Catalyst. A chemical that increases the rate of a chemical reaction without itself being changed by the reaction. (Hydrogen Peroxide) Active Site.An uncompetitive inhibitor interacts with the enzyme-substrate complex, but not with the enzyme alone. For uncompetitive inhibition, the double-reciprocal equation is as follows: 1/V 0 = α'/V max + K m /V max • 1/[S] the reciprocal of V 0 equals alpha prime divided by V max plus K m divided by V max times the reciprocal of the substrate's ...ADH. Alcohol Dehydrogenase (ADH) is the enzyme that catalyzes the first step in the metabolism of alcohol in humans. ADH catalyzes the oxidation of a broad range of substrates containing hydroxyl groups, including ethanol. In the case of ethanol, the alcohol is converted into acetaldehyde, another toxic compound, which is then metabolized further.

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 ...

Describe a zero order reaction rate. Rate is independent of [S] but proportional to [E] or another factor. Describe first order reaction rates.V m a x is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V m a x is called the K m , and is a useful measure of how quickly reaction rate increases with substrate concentration. K m is also a measure of an enzyme's affinity for (tendency to ... 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 chemical reactions that are catalyzed by enzymes.
