- 15.13) The NADH that is produced by glycolysis is not able to pass through the inner mitochondrial membrane to enter the matrix region and undergo oxidative phosphorylation. Name the two processes in which the energy from NADH made in glycolysis can enter the mitochondrial matrix. ANSWER: 1) malate-aspartate shuttle 2) glycerol 3-phosphate shuttle EXPLANATION: Oxidative phosphorylation requires that NADH be located within the mitochondrial matrix. Since pyruvate oxidation/decarboxylation and the reactions of the citric acid cycle occur in the mitochondrial matrix, the NADH created in those processes can immediately undergo oxidative phosphorylation. The NADH that is produced by glycolysis is able to pass through the outer mitochondrial membrane and enter the intermembrane space; however, it is not able to pass through the inner mitochondrial membrane to enter the matrix region. In order for the energy from this NADH to be utilized, it must be processed through "NADH shuttles." The two…20.12 Classify the enzyme that catalyzes each of the following reactions: |3| a.

- Consider the typical beta oxidation of linoleic acid (C18:2 ^Δ9, 12): How many ATP are generated in complete oxidation of linoleic acid? How many NADH are generated in complete oxidation of linoleic acid? How many FADH2 are generated in complete oxidation of linoleic acid?Why does methotrexate prevent import of dihydrofolate reductase (DHFR) into mitochondria?14 15 Why doesn't the net reaction for the citric acid cycle have intermediates (citrate, isocitrate, a-ketoglutarate, succinyl-CoS, succinate, fumarate, malate and oxaloacetate)? The free energy change for the pathway in a respiring mitochondrion is zero. The intermediates are not involved in energy production. The two carbons from acetyl-CoA are not converted to CO₂ in the first cycle. All reactions of the citric acid cycle are coupled through intermediates of the pathway. AGo for the citric acid cycle is -41 kJ/mole, indicating an equilibrium that favors products. Under what circumstances would the citric acid cycle be at equilibrium? No molecular oxygen Electron transport in blocked by an analog of CoQ. No more pyruvate. The wrong political party wins the next election.
