Which of the following metabolic pathways does NOT takes place in muscle cells? Tricarboxylic acid cycle Glycogenesis Glycogenolysis Conversion of ketone bodies to acetyl CoA Pentose phosphate pathway

If the alpha-ketoacid product from the transaminase reaction that uses alanine and alpha-ketoglutarate as substrates goes on to make glucose via the __________ pathway, then the amino acid carbon skeleton is considered to be __________.     ANSWER       citric acid cycle; ketogenic   glycogen synthesis; ketogenic   glycolysis; glucogenic   gluconeogenesis; glucogenic

What essential compound is produced in the pentose phosphate pathway that is needed for synthesis as well as for defense against oxidative damages? NADH AMP ADP FADH2 NADH ATP

The net ATP produced during a β-oxidation process is always less than two ATP because An ATP is converted to ADP during fatty acid activation ATP is consumed during acyl CoA shuttling An ATP is converted to AMP during fatty acid activation A NADH is produced in the cytosol

The complete catabolism of glucose into CO2 and H2O generally yields a smaller amount of ATP in aerobic eukaryotes than in aerobic prokaryotes because the aerobic eukaryotes: generate more molecules of FADH2 during aerobic respiration have transport costs to get NADH into the mitochondrion generate more molecules of NADH during aerobic respiration are able to use pyruvate as a substrate for fermentation always produce ethanol rather than lactic acid as a byproduct

Which is both an input and an output of a metabolic pathway?     Acetyl-CoA     Oxaloacetate     Citrate     GTP

Which enzyme in ß-oxidation extracts two electrons from the fatty acid, resulting in the eventual generation of 1.5 ATP each time that it catalyzes a reaction? O Acyl-CoA dehydrogenase O succinate dehydrogenase O L-hydroxyacyl-CoA dehydrogenase O Enoyl-CoA hydratase

Which of these processes is most exergonic? (Think VERY carefully!)     Dephosphorylation of glucose     Conversion of enol to keto     Oxidation of an aldehyde to a carboxylic acid group.     ATP hydrolysis

Inhibiting which of the following enzymes will block gluconeogenesis but not glycolysis?   Pyruvate carboxylase   Pyruvate kinase   Phosphoglycerokinase   Phosphenolpyruvate carboxykinase   Phosphofructokinase-1
