Which of the following statements is true for the shown reactions? Deficiency of oxaloacetate stimulates the formation of X and y Insulin signaling stimulates the formation of X and Y Both A and B Neither A nor B
Which of the following enzymes catalyze a reaction where a ketone is converted to an acid? Alpha-ketoglutarate dehydrogenase Glyceraldehyde 3-phosphate dehydrogenase Pyruvate decarboxylase Fumarase Hexokinase
Pyruvate can be converted to glucose via gluconeogenesis, or it can be oxidized to acetyl-CoA for energy production. The enzyme pyruvate carboxylase is regulated allosterically by which of the following? Oxaloacetate All of the above Acetyl COA Glucose-6-phosphate Fructose-6-phosphate
help with filling in the blanks The amino acid [alanine/aspartate/glutamate] can be transaminated to a- ketoglutarate, the amino acid [alanine/aspartate/glutamate] can be transaminated to pyruvate, and the amino acid [alanine/aspartate/glutamate] can be transaminated to oxaloacetate. As a result, all three amino acids are considered [glucogenic/ketogenic/metagenic]. The carbon of urea comes directly from [carbon dioxide/a-carbon of an amino acid/glucose]. The nitrogen atoms in urea come from [ammonia/DNA/pyruvate] and [aspartate/glutamate/alanine] directly.
Glutamate is derived from which of the following molecules? oxaloacetate pyruvate O 3-phosphoglycerate chorismate O a-ketoglutarate
Alcohol consumption on an empty stomach results in some interesting biochemical as well as embarrassing behavioral alterations. We will ignore the lat t er. Gluconeogenesis falls; there are increases in intracellular ratios of lactate to pyruvate, of glycerol 3- phosphate to dihydroxyacetone phosphate, of glutamate to α - ketoglutarate , and of D-3- hydroxybutyrate to acetoacetate. Hypoglycemia develops rapidly Blood pH also falls. Alcohol consumption by a well - fed individual does not lead to hypoglycemia or alteration in blood pH . (a) Why does ethanol consumption result in the altered ratios? (b) Why does hypoglycemia and blood acidosis result in the hungry individual? (c) Why does the well-fed person not experience hypoglycemia?
Citrate synthase mediates the transfer of what functional group to produce citrate from Oxaloacetate?
What is the term transamination means in amino acid metabolism? Provide examples; how does it differ thanOxidative Deamination?
The first step of gluconeogenesis involves the carboxylation of pyruvate and has a large negative delta G (i.e very exergonic). Explain how it is possible that this step can be exergonic if we know that adding CO2 onto molecules is fundamentally a destabilizing phenomenon?
What enzyme will not be used if the oxidative portion of the pentose phosphate pathway is operating to produce ribose 5-phosphate? Ribulose 5-phosphate isomerase 6-phosphoglucono-lactonase 6-phosphogluconate dehydrogenase Transaldolase
