WebSep 1, 2014 · The Michaelis-Menten equation (see below) is commonly used to study the kinetics of reaction catalysis by enzymes as well as the kinetics of transport by transporters. Typically, the rate of reaction (or reaction velocity) is experimentally measured at several substrate concentration values. WebCompetitive inhibition. Inhibition. So the classic case of competitive inhibition: if there's some molecule that competes for the substrate at the active site, as we'll see this isn't the only form of competitive inhibition, but this is the one that you will most typically see in a textbook. So that's our enzyme again.

WebLiving systems depend on chemical reactions which, on their own, would occur at extremely slow rates. Enzymes are catalysts that reduce the needed activation energy so these reactions proceed at rates that are useful to the cell. The study of enzyme kinetics can help us understand the function and regulation of enzymes. WebBasic enzyme kinetics graphs. Graphs like the one shown below (graphing reaction rate as a function of substrate concentration) are often used to display information about enzyme kinetics.
