And in the final step, we're going to basically use this high energy in the bond to attach that molecule onto that Pyruvate to form the oxyloace. So, once again, the bond holding the CO2 and the biotin enzyme together is quite unstable and quite reactive. And so when we cleave that in the next step, that will release 20 kilojoules of energy per mole that we actually use up. So in the final step, we have the enzyme Biden CO2 complex that we basically formed here that is mixed with that Pyruvate molecule and that forms that oxalo acetate. So we're able to actually use this very activated and reactive complex to attach that CO2 on the oxyloacetate molecule. And so if we sum up these reactions, we essentially get this net reaction here.
