So let's move on to step six, seven, eight, the final three steps of the citric acid cycle. So these are our three steps. Now remember that the citric acid cycle begin with an oxyloacetate intermediate. And because the citric acid cycle is literally a cycle, so if we begin with an oxyloacetate. What that means is we have to end up with that same oxyloacetate. And so what this process involves is in these three steps six, seven, eight, we transform the four carbon succinate into the four carbon oxyloacetate.
