The Michaelis constant, K m, is a parameter in the Michaelis-Menten equation.K m is equal to the substrate concentration where the corresponding reaction rate is ½ • V max.An enzyme with a low K m, therefore, achieves its half-maximal velocity at a low substrate concentration, while an enzyme with a high K m needs high substrate concentrations to achieve this velocity.Conclusion Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative pathway of lower activation energy. In this lab, an investigation was brought forward to discover the factors that can affect the enzyme during catalytic activity; the following conclusions were made from conducting the lab. ...Enzyme kinetics.

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 ...Investigate Alcohol Flush Syndrome by studying Alcohol Dehydrogenase kinetics.

Share free summaries, lecture notes, exam prep and more!!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.his courses using Labster and assess the shift. In 2016, he essentially copied Bonde’s proce - dure, using a Labster simulation of enzyme kinetics.
