Now, if we sum these values up, so 33.5 plus 22.2 basically gives us 55.7 and then 55.7 plus 16.7 gives us 72.4. So basically these three steps alone release 72.4 kilojoules of energy every time a single glucose molecule is broken down. And that makes up the predominant amount of this total 96.2 kilojoules per mile. So what that basically means is for gluco neogenesis to actually take place effectively, it must somehow be able to bypass these three steps. In fact, that's exactly what happens as we'll see in a future lecture. Gluconeogenesis and glycolysis actually have seven steps in common, but three steps are not in common and it's these three steps.
