Enzyme inhibition plots
WebHanes–Woolf plot. In biochemistry, a Hanes–Woolf plot, Hanes plot, or plot of against , is a graphical representation of enzyme kinetics in which the ratio of the initial substrate concentration to the reaction velocity is plotted against . It is based on the rearrangement of the Michaelis–Menten equation shown below: WebStudy with Quizlet and memorize flashcards containing terms like A variety of factors influence enzyme activity. Substances that bind to the enzyme and interfere with substrate binding or catalysis are inhibitors.
