The shape of the curve in the graph is 'hyperbolic'.
By increasing the concentration of enzyme catecholase the maximum reaction rate greatly increases. So, enzymes can speed up the rate of the reaction. Enzyme catecholase becomes saturated at high catechol concentration. For a catecholase-catalyzed reaction, a hyperbolic relationship is established between the rate of the reaction and the concentration of catechol. Catecholase catalyzes the response of catechol and oxygen and is the protein that makes wounded or generally harmed natural products become brown. Within the sight of catecholase, catechol is oxidized to frame benzoquinone, which has a rosy earthy-colored tone.
