The ...Vmax = k2[E]0. and after rearrangement, we have this equation: kcat = k2 = Vmax [E]0. That is the equation for calculating catalytic efficiency, to be used after we obtain data from experiments and after using the Michaelis-Menten equation. With a larger k cat , the enzyme is efficient because less enzyme is needed.Abstract. There are many factors which are known to cause variability in human in vitro enzyme kinetic data.

LabsterThe 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.We will compare which is higher/lower than the control.
