Now, we also use the phosphate to form that GTP, and we basically released the coenzyme A that went into the reaction in step number four. Now, stage number three are basically steps six, seven and eight. And the entire purpose of these steps is to basically regenerate our molecule, the oxalo acetate, the four carbon molecules that we'll need to use again to basically undergo the reaction. This process the cycle a second time because we have that second acetyl, coenzyme A. So the final three steps six, seven and eight of the citrix cycle involves the regeneration of our oxalo acetate molecule. The question is, how exactly does this take place?
