Solution
The correct option is A Allosteric
Allosteric enzymes are the enzymes which possess an allosteric site for binding of allosteric modulators in addition to the active site for binding of substrate molecules. A non allosteric enzyme or an enzyme which follows Michalis-Menten kinetics shows a hyperbolic curve for rate of chemical reaction plotted against substrate concentration. An allosteric enzyme on the other hand shows a sigmoidal curve.So, the correct answer is 'Allosteric'
