At low concentrations of CTP somewhere here, the rate of production will be high somewhere here. But as we increase the concentration of CTP, the rate will drop. And that's because now we have ample amount of CTP and some of them will go back and bind onto this enzyme, basically inhibit that enzyme. And that decreases the rate of production of this intermediate molecule. And that makes sense because if we have abundant amounts of CTP we do not want to waste energy and produce this intermediate molecule. And so that's exactly why we limit the production of n carbon oil aspartate by controlling the activity of this enzyme alospa.
