To destabilize and split apart glucose molecules to make ATP To convert pyruvate to acetyl-CoA, producing CO2 and a high energy electron carrier To use the energy stored in acetyl-CoA to make ATP and high energy electron carriers To fix carbon dioxide to produce G3P, which is used to make glucose

Complete oxidation of a 16-carbon fatty acid can yield 129 molecules of ATP Study Figure 19.2 and determine how many ATP molecules would be generated if a 16-carbon fatly acid were metabolized solely by the TCA cycle, in the form of S acetyl-CoA molecules.
Using the answer code on the right, indicate which form of energy production is being described: 1. takes place in the mitochondrial matrix 2. produces H2O as a by-product 3. results in a rich yield of ATP 4. takes place in the cytosol 5. processes acetyl-CoA 6. takes place in the mitochondrial innermembrane cristae 7. converts glucose into two pyruvate molecules 8. uses molecular oxygen 9. accomplished by the electron transport system and ATP synthase (a) glycolysis (b) citric acid cycle (c) oxidative phosphorylation
in the mitochondria pyruvate is converted into acetyl CoA so then acetyl CoA make its way to the TCA cycle and produces energy sources for oxidative phosphorylation. Pyruvate oxidation transforms pyruvate, a three-carbon molecule, into acetyl, a two-carbon molecule linked to Coenzyme A, generating NADH and releasing one carbon dioxide molecule in process the citric acid cycle is fundamental because runs on acetyl CoA as its fuel. i need more explanantion
Krebs cycle products/acetyl CoA molecule are 4 CO2, 3 NADH, 1 FADH2, 2 ATP 4 CO2, 6 NADH, 2 FADH2, 2 ATP 2 CO2, 3 NADH, 1 FADH2, 1 ATP 6 CO2, 6 NADH, 2 FADH2, 4 ATP
The synthesis of acetyl-CoA from pyruvic acid serves as a bridge between which of the following pathways? glycolysis and the Krebs cycle the Entner-Douderoff pathway and the Krebs cycle CO glycolysis and fermentation glycolysis and the electron transport chain Krebs cycle and the electron transport chain uestion 21 the carbon dioxide produced during aerobic respiration is produced in the Krebs cycle
Each acetyl CoA that enters in the citric acid cycle, 2 carbon dioxide molecules are released in reactions which are coupled with the production of NADH molecules from reduction of NAD+ molecules and FADH2 is alse released by reduction of FAD+. NADH and FADH2, pass their electrons to the electron transport chain, turning back into NAD+ and FAD+ Explain further
