Imagine, if instead of metabolizing glucose to pyruvate using enzymes, we got energy by burning glucose in O 2 C 6 H 12 O 6 + 6O 2 ====> 6CO 2 + 6H 2 O + energy How much energy could we get burning glucose in O 2 ? Enough for about 60 to 70 ATPs. How much ATP did we make in glycolysis?

Glycolysis: glucose ===> 2 pyruvates (makes 2 ATPs) This is really pathetic !

Oxidize the pyruvate from glycolysis all the way to CO 2 . This is what the citric acid cycle does. Next:

Chapter 13 - The citric acid cycle (chapter 11 of 1 st edition) The citric acid cycle naturally follows glycolysis, since it describes something that pyruvate can be used for! Known as the “ citric acid cycle ” or “ Krebs cycle or “ tricarboxylic acid cycle ” or “ TCA cycle ”.
