WebbGeneral Equation (2) can be applied to mixed type inhibition, and we rearrange this equation as follows: 6 A relationship of ( V – v )/ v with [I] shows a straight line converging at –Ki and –Ki/K’i in the third quadrant. We can calculate the K’i value from this point ( Figure 4 ). Figure 4. Quotient velocity plot for mixed type inhibition. WebbComputing Ki for a Competitive Enzyme Inhibitor 1 A competitive enzyme inhibitor interferes with binding of substrate to enzyme so as to raise the K m value without affecting V max. Competitive inhibition is overcome by increasing substrate concentration. A competitive inhibitor I increases the “apparent” value of K m according to the ...

Webb9 mars 2024 · Corrosion inhibition of mild steel in 1 M HCl was investigated in the absence and presence of potassium iodide (KI) as a corrosion inhibitor. The effects of temperature and inhibitor concentration were studied using weight loss technique. The result obtained shown that KI act as an inhibitor for mild steel in HCl and decreases … WebbWhen I/Ki was even as high as 1 (i.e. 50% inhibition), the noncompetitive inhibition model was identified only 3.3% of the time; usually, the competitive inhibition model was incorrectly identified as the model. When I/Ki = 10, the extent of inhibition reached 90%, allowing the noncompetitive inhibition model to be correctly identified all the ...
