Significance of Km and Vmax - Science Gateway

WebAug 23, 2024 · V = Vmax [S] / (Km + [S]) This is the mathematical expression that is used to model your experimental kinetic data It is known as the Michaelis-Menten equation Experimental approach The general approach is to add a known concentration of substrate to the enzyme and to determine the initial reaction rate for that concentration of substrate WebKm is a constant that describes an enzymes affinity for its substrate. It is defined at the concentration of substrate where the reaction velocity is exactly half of Vmax. The way to think about it is the lower the Km, the less substrate concentration needed for an enzyme to be working at full capacity. movies smitty\u0027s sanford maine

WebVmax stays the same, Km is changed and is higher because it takes more substrate concentration to reach 1/2Vmax. Describe Noncompetitive inhibitors: Inhibitor binds to enzyme at a different site than the active site and this changes the shape of the enzyme's active site and decreases its ability to bind to the normal substrate. WebThe Lineweaver-Burk double reciprocal plot for this set of data shows a series of parallel lines - both Km and Vmax are reduced: top of page. The choice of a competitive or non-competitive inhibitor as a drug. If the requirement is to increase the intracellular concentration of the substrate, then either a competitive or non-competitive ... WebV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus.
