In humans, neural tube closure defects occur in about 1 in every 1000 live births. Failure to close the neural tube can result from both genetic and environmental causes. A recent report has demonstrated that zinc deficiency disrupts neural tube closure by:

Consider an enzyme catalysed reaction treated with inhibitor. Enzyme kinetic was analysed with Eadie Hofstee equation. A plot of V0 versus V0/[S] for an enzyme-catalyzed reaction is shown below. The control curve was obtained in the absence of inhibitor. Which effect is shown on the enzyme activity when an inhibitor is added to the reaction mixture?
