So in this step, what we want to do is we want to essentially kick off this carbon dioxide shown in blue and replace that with a coenzyme a, which is what we have in this particular case. In the process, we also abstract our electrons a hydride IoT and we place it onto the NADH or the NAD to form the NADH. So the NAD is reduced and the alpha key to gluten rate is oxidized. We release the carbon dioxide and an H plus I and notice we attach the coenzyme A. So we form this very high energy bond known as the Thio ester bond. So this is essentially the same bond that we have here.
