Calculate ATP yield formed from oxidation 1 mole lactic acid untill CO₂ and H₂O:

Answer 1

1. They decompose complex sugars such as starch and act at α-1,4-glycosidic bonds.
   
2. Ammonia and an aldehyde.
3. The citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
4. Coenzyme Q (CoQ) and cytochrome c (Cyt c).
5. Oxygen active species are Oi- (superoxide) and its conjugate acid the hydroperoxyradical HOi, singlet oxygen '02, the hydroxyl radical 'OH and hydrogen peroxide H202.
6. It involves the release of lactate by muscle, it involves ATP synthesis in the muscle and it involves the release of glucose by the liver.
7. Five enzymes are involved: carbamoylphosphate synthase (CPS), ornithine carbamoyltransferase (OCT), argininosuccinate synthase, argininosuccinate lyase, and arginase.
8. The pyruvate dehydrogenase complex (PDC)³ catalyzes the oxidative decarboxylation of pyruvate with the formation of acetyl-CoA, CO₂ and NADH (H⁺) (1,–3).
9. Phosphoenolpyruvate.
10. Amino acid.
