- To export acetyl CoA from the mitochondrial matrix, the molecule must be condensed with which major metabolic intermediate? pyruvate glucose fumarate oxaloacetate a-ketoglutarate succinyl CoA citrateIn the presence of O₂ and low energy status of the cell, acetyl CoA is oxidized to oxygen lactate carbon dioxide ethanol O NADHGive an account of β – oxidation of saturated even carbon fatty acid (Palmitic acid)along with the total ATPs obtained.
- Carnitine shuttle is used to Transport FA chains from the adipose tissue to the liver. Transport FA chains from the blood-stream to the cytosol. Transport FA chains from the cytosol to the mitochondrial matrix. Transport FA chains from the mitochondrial matrix to the cytosol.Pyruvate can be converted into two different products depending on whether oxygen is readily available or not. Under conditions of strenuous activity (anaerobic) the product is: аcetyl CoA pyruvate lactate CO2Although the outer mitochondrial membrane is permeable to all small molecules, the inner mitochondrial membrane is essentially impermeable in the absence of specific transport proteins. Consider this information answer: If the inner mitochondrial membrane were rendered as permeable as the outer membrane, how would that affect oxidative phosphorylation? Which specific processes would stop and which remain?
- In which of the following citric acid cycle reactions does the coenzyme FAD participate? * citrate - isocitrate O succinate - fumarate O malate - oxaloacetate O more than one correct response O no correct responseIn beta-oxidation, which cofactor is required the for second oxidation reaction (conversion of beta-hydroxyacyl-CoA to beta-ketoacyl-CoA)? NAD+ water FAD CoA-SHAlthough the outer mitochondrial membrane is permeable to all small molecules, the inner mitochondrial membrane is essentially impermeable in the absence of specific transport proteins. Consider this information answer: Present two types of benefits derived from separating the reactions of glycolysis in the cytosol from those that occur during the citric acid cycle in the mitochondrion.
- Fill in the bold using the table. Because the inner mitochondrial membrane is impermeable to L, when there is an excess of mitochondrial L, it converts to M using a TCA condensation reaction, M crosses to the cytosol using a designated transport system. In the cytosol, M reconverts to L and oxaloacetate. Oxaloacetate is subsequently converted to malate with simultaneous production of N, a prerequisite cofactor for the glycolysis pathway. This reaction is then followed by conversion of N to pyruvate which produces O, a prerequisite cofactor for the fatty acid synthesis pathway. L M N O A. ATP pyruvate malate NADPH B. ATP citrate ATP NAD+ C. acetyl CoA pyruvate NAD+ NADH D. acetyl CoA citrate NAD+ NADPH E. glucose pyruvate malate NADP+In liver, the accumulation of which of the following metabolite attenuates the inhibitory of ATP on phosphofructokinase? * O Fructose-2,6-Bisphosphate Fructose-1,6-Bisphosphate Glucose-6-Phosphate O CitrateWhat mitochondrial enzyme catalyzes this reaction? "ooc, COA "OoC + H* Co2 COA + "00C NH,+ HN Delta-aminolevulinate synthase Porphobilinogen synthase None of these is correct. Uroporphyrinogen III synthase
