Km and vmax explained
WebThe substrate concentration at which the reaction rate is halfway to V max (i.e., ½ V max) is called the Michaelis constant (K m). K m is a representation of the affinity between an … WebThe larger the kcat is relative to koff, the greater the difference between KD and KM. Briggs and Haldane made no assumptions about the relative values of koff and kcat, and so Michaelis-Menten kinetics are a special case of Briggs-Haldane kinetics. The opposite extreme, where kcat >> koff , is called Van Slyke-Cullen behavior ( 3 ).

Most of the time K cat just equals K 2 (NOT the case when there are more reaction steps)
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.
WebMixed inhibition. a possible mechanism of non-competitive inhibition, a kind of mixed inhibition. Mixed inhibition is a type of enzyme inhibition in which the inhibitor may bind to the enzyme whether or not the enzyme has already bound the substrate but has a greater affinity for one state or the other.
