Why is it critical that NAD* and FAD be regenerated inside the mitochondrial matrix rather than the cytosol? Because they maintain flux through the citrate cycle. Because anabolic reactions generally require them. Because they transport pyruvate through the matrix. Because they produce GDP through the citrate cycle.

- How Do Vitamin-Derived Coenzymes Aid Metabolism? What chemical functionality is provided to enzyme reactions by pyridoxal phosphate (we Chapter 13)? By coenzyme A (see Chapter I9)? By vitamin B12 (see Chapter 23)? By thiamine pyrophosphate (see Chapter 19)?Which of the following steps DO NOT occur in pyruvate oxidation? A. Addition of Co-A B. Oxidation Of NAD+ C. Production of CO2 D. Oxidation of PyruvateIn order to metabolize lactose, most infants express the enzyme lactase in their intestines. How many pyruvate molecules and NADH molecules can be generated in glycolysis from one lactose molecule? Please explain. How many ATP molecules will be used and generated by 1 lactose molecule? Please explain.
- Which of the following events does not occur during pyruvate processing (pyruvate oxidation)? One carbon atom of each pyruvate is oxidized to carbon dioxide. NAD+ coenzyme is reduced to NADH. The remaining two carbon atoms of pyruvate (acetyl unit) reacts with coenzyme A to produce acetyl CoA. FAD coenzyme receives two hydrogen atoms to produce FADH2.The Krebs cycle converts ________ through a cycle ofreactions. In the process, ATP, ________, and ________ areproduced.a. acetyl CoA; FAD, NADb. acetyl CoA; FADH2; NADHc. pyruvate; NAD; FADH2d. pyruvate; oxygen; oxaloacetateHow many ATP molecules can be synthesized from four Acetyl CoA molecules if all four enter the Kreb's Cycle? Assume the energy yielding products enters the ETC.
- ___ molecules of ATP are ultimately formed per every acetyl-CoA that enters the citric acid cycle and the remaining ATP molecules are generated via the ___ of NADH and FADH2. A) Nine; oxidation B) Ten; reduction C) Ten; oxidation D)Nine; reductionCompare and contrast pyruvate metabolism in themitochondrion and the hydrogenosome.In order for an adipose cell to synthesize decanoic acid, it will need substrates in the form of _______ ATP, _______ NADPH from the transport of citrate into the cytoplasm and the subsequent recycling of oxaloacetate, and _______ NADPH from the pentose phosphate pathway. You can ignore the ATP used to regenerate mitochondria oxaloacetate via pyruvate carboxylase.
- 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 explanantionIn the conversion of glucose into two molecules of lactate, the NADH generated earlier in the pathway is oxidized to NAD +. Why is it not to the cell’s advantage to simply make more NAD+ so that the regeneration would not be necessary? After all, the cell would save much energy because it would no longer need to synthesize lactic acid dehydrogenase.Peroxisomes will convert acetaldehyde using_______NAD+ into acetyl-COA
