Energy production involves glycolysis or beta-oxidation, leading to the Krebs cycle and electron transport chain to produce ATP.

“first is glycolysis we take glucose which is a six carbon molecule we break it in half to make two pyruvates right that when we do that we make a little bit of ATP that pyruvate then is converted to something called a cetal COA we run that through the kreb cycle where we're also making ATP but we then we're making these intermediate products one of those intermediate products and the main one is something called nadh that nadh is then shuttled to the mitochondrial membrane for you know this is the magic where we make the most ATP”
