The mitochondria is proposed that it's come from an early bacteria. So within their cytoplasm and then they'll be moving stuff across their membrane, which we'll discuss in a second. What we've now produced that we're going to utilize to make the new fantastic thing, right? We're putting the car using that analogy, right? From glycolysis, we've produced two NADH. The transformation of pyruvate to acetyl-CoA, we'veproduced two more NADH. And through the Krebs cycle, we've produce six NADH and two FADH2. That's four carbon dioxide, six NADH, two FAD
