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 ...

We would like to show you a description here but the site won't allow us.How the changes in substrate concentration (PNPP), changes in temperature, changes in phosphat and the presence of an inhibitor (phosphate ions) effects the rate of reaction in the reaction between PNPP andVmax = 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.

The modern scientists have a deep understanding of enzyme kinetics. The purpose of this laboratory report is to confirm previous findings covered in various sources of scientific literature and journals. Enzymes are often described as ‘organic catalysts which increase the rate of reaction of a bio-chemical reaction’ ( David L.Nelson etal 2008).

The pH at which the rate or a suitable parameter is a maximum is called the pH optimum and the plot of rate or parameter against pH is called a pH profile.

Since allosteric enzymes are cooperative, a sigmoidal plot of \(V_0\) versus \([S]\) results: There are distinct properties of Allosteric Enzymes that makes it different compared to other enzymes. One is that allosteric enzymes do not follow the Michaelis-Menten Kinetics. This is because allosteric enzymes have multiple active sites.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. About Virtual Labs for Biology.
